Sorption Overview Series #6
Demystifying Sorption Methods: A Quick Comparison for Better Research Decisions
As we conclude our ‘Sorption Overview’ series, we’ve examined the key experimental techniques used to measure gas and vapor sorption: gravimetric, volumetric, and chromatographic methods. Each technique provides valuable insights into fundamental material properties and helps evaluate material performance across a wide range of applications.
Refer to the comparison chart below to help determine which method best suits your research needs.

Gravimetric Method
Gravimetric techniques determine gas or vapor uptake by directly measuring changes in sample weight using a highly sensitive microbalance. As conditions such as temperature and pressure or vapor concentration change, the balance detects shifts in net force, which correspond to the amount of sorbate absorbed or adsorbed by the material.
Because they rely on precise weight measurements, gravimetric methods such as Dynamic Vapor Sorption (DVS) are considered among the most accurate techniques for sorption analysis. They are especially useful for studying a wide range of materials under controlled and variable environmental conditions.
| Sample Mass Uptake
In a standard experiment, the sample is loaded in the balance and isolated in a chamber. The chamber temperature is carefully monitored, alongside the pressure/concentration of the gas phase. Change in mass given by the balance has three contributions: the change in sample mass given by uptake in the sample, a change in net buoyant force given by the change in density of the gas phase and a drag force of a gas flow on the sample pan. Buoyancy Force The buoyancy force is small for experiments at ambient pressure and temperature but can play a role at high pressure (>a few bar) where corrections may be required. Drag Force The drag force is only relevant when a dynamic mode is used, as the gas flow impinges on the balance parts and may need to be corrected through a blank. A way of minimizing both drag and buoyancy corrections is to construct the balance symmetrically, having a sample and a reference pan in identical configurations in the flow path. Experimental Design
Advantages of Gravimetric Methods One of the key advantages of gravimetric sorption methods is their flexibility in sample size. For single-component measurements, as little as 1–5 mg of material is often sufficient to yield highly reliable results. At the same time, gravimetric systems can accommodate much larger sample sizes, handling several grams or tens of cubic centimeters, depending on the material and application. The accuracy and range of measurements are directly tied to the performance and stability of the microbalance. For example, Surface Measurement Systems (SMS) offers advanced gravimetric analyzers with exceptionally high resolution:
This combination of precision and versatility makes gravimetric methods ideal for both delicate, small-scale experiments and larger, industrially relevant studies. Challenges and Considerations While gravimetric sorption techniques are known for their high sensitivity and accuracy, there are a few practical considerations to keep in mind. Gravimetric systems typically require a stable laboratory environment, particularly with respect to temperature and vibration control, to ensure consistent results. Additionally, extended equilibration times may be needed for certain materials or conditions, especially when studying slow diffusion processes. |
Volumetric Method
In volumetric methods, a cell containing the adsorbent material is dosed sequentially from a known volume of gas. The pressure is monitored as the probe sorbs into the material, and the equilibrium pressure is then used to calculate the final amount of gas remaining in the cell using an equation of state. The difference between the initial and final amounts of gas is equal to the amount adsorbed.
Sample Uptake
Advantages of Volumetric Methods
Challenges and Considerations Volumetric sorption techniques rely on indirect measurement via pressure, which introduces several important limitations:
|
Chromatographic / Breakthrough Methods
In chromatographic methods, the probe molecule flows through a packed bed or column containing the material to be characterized. Key variables including temperature, total pressure or concentration, and flow rate are continuously monitored at both the inlet and outlet of the column. These measurements allow for the calculation of a molar mass balance across the packed bed, providing insight into the sorption behavior of the material under dynamic flow conditions.
| Method Modes Chromatographic and breakthrough methods are dynamic flow techniques used to study how probe molecules interact with packed columns. Most systems operate in a carrier mode for easier pressure control. Probe introduction typically happens in two ways:
Experimental Process A sample-packed column is weighed before and after preparation, with thermal activation applied if needed. The system’s dead volume is measured using a non-interacting gas pulse. The probe pulse or front passes through the column, and sensors measure outlet concentration and flow to determine uptake via mass balance. Challenges and Considerations Controlling temperature, pressure, concentration, and flow precisely makes this method complex. It requires larger sample amounts (hundreds of mg to grams) and can be scaled for industrial simulation. Sample form affects performance, as fine powders may cause blockages. Additional Capabilities These methods uniquely provide multicomponent adsorption data and insight into adsorption kinetics critical for scaling processes. Surface Measurement Systems offers the iGC-SEA and BTA Frontier analyzers as leading tools for these analyses.

They are especially useful for studying a wide range of materials under controlled and variable environmental conditions.
Dynamic (Flowing)
In the dynamic method, a continuous flow of gas or vapor is passed over the sample. The method controls both the upstream rates of entry and the downstream exit rate, effectively controlling both the pressure/concentration and flow rate of the adsorbate in the chamber. It also helps to overcome some boundary layer diffusional barriers, by ensuring little to no concentration gradients around the sample. Both pure and carrier introduction is possible.
Note: The SMS DVS, SMS iGC-SEA and SMS BTA systems operate in dynamic mode, while the SMS DVS Vacuum can perform both static and dynamic introduction.

Do the results differ?
Interestingly, the number of probe molecules that interact with the material is the same in both methods. As illustrated in Figure 2, the equilibrium uptake is typically similar, regardless of the introduction method. However, the kinetics of sorption can vary, with carrier gas mode often offering a more accurate picture of how materials behave under practical conditions.
It’s important to note that for certain materials, even the choice of carrier gas may impact sorption behavior, so careful selection is essential.
Which Method Should You Use?
Both techniques are powerful tools in surface and materials science. The choice depends on your experimental goals:
- Choose pure mode when maximum control and absolute data are required.
- Opt for carrier mode when simulating realistic environments or studying sorption kinetics

Each technique provides valuable insights into fundamental material properties and helps evaluate material performance across a wide range of applications.
Refer to the comparison chart below to help determine which method best suits your research needs.
The Role of Temperature in SorptionThe average kinetic energy of all molecules in the system is unambiguously defined by temperature. Temperature is represented in Kelvin (K, the SI unit), degree Celsius (°C) or degree Fahrenheit (°F). Although measuring temperature accurately and ensuring its homogeneity throughout an instrument can be challenging, this discussion will focus on the relationship between temperature and kinetic energy. On the other hand, the number of target probe molecules which interact with the material at any point can be reported in a variety of ways, with terms such as pressure, absolute/partial pressure, relative pressure, humidity, water activity, volume/molar fraction and concentration, etc. The variety of terms will be discussed in more detail. |
Understanding Pressure and its VariantsAbsolute Pressure Total and Partial Pressure Fraction and Concentration One further complication is that the fraction can be either on a molar, volume, or mass basis of the components. The best way to represent the meaning of a fraction basis is through an example. In a balloon we put one mole of N2 and one mole of CO2. The molar fraction of N2 is 1/(1+1) = 0.5 in this mixture. To get the volume fraction, we must instead consider the volume contribution of each gas. If we consider both gases as ideal, a mole of each occupies 22.4 L, so for N2 the volume fraction is 22.4/(22.4+22.4) = 0.5. Finally for the mass fraction, we need to convert to weight by using the molar mass of each component, resulting in 28g of N2 and 44g of CO2. The mass fraction of N2 is then 28/(28+44) = 0.388. To differentiate between the three, we often use notation such as mol%, vol% and wt%. Sometimes fractions are also expressed as parts of a whole, e.g. parts-per-million or ppm. These can be converted into a regular fraction by dividing by the total number of parts. It is also important to refer to which basis these refer to, by using notation such as ppmv or ppmw, etc. These units are generally discouraged as they are confusing. Relative Pressure, Humidity and Water Activity |
|
| The formula for relative pressure is |
| Relative pressure is usually represented with the shorthand p/p0, ranging from 0 to 1, or from 0 to 100% if using a percent value. Humidity (RH) or water activity are both relative pressure terms, specifically used when the vapor is water. |
Critical Points and Relative Pressure
Above the critical point of a compound, there is no distinction between a liquid and gas state, which means that there is no vapor pressure. Such gases (for example N2 and CH4 at room temperature) cannot be represented in a relative pressure.
Figure 1 summarizes the different ways or reporting total pressure.
