The salt spray test involves placing samples inside a chamber where a fine mist of salt solution is continuously sprayed. The environment inside the chamber is maintained at controlled temperature and humidity levels to accelerate the corrosion process. Over a specific duration, the samples are observed for signs of rust, coating ...
With high-power industrial-grade laser and a robust sampling fan, the device actively pulls in air at a stable flow rate, providing a consistent sample to the optical chamber and securing both accuracy and repeatability in particulate detection. ...
Procedure of the Assay The Caco-2 permeability assay is typically conducted using a two-chamber system. The apical side represents the intestinal lumen, while the basolateral side simulates the bloodstream. During the assay, a test compound is introduced to the apical chamber, and the permeation of the compound through the Caco-2 monolayer is monitored over time. ...
Size distribution analysis of microsized water particle mist generated from an odor control technology showed the major- ity of particles to be in the low micron range. The indirect detection and determination of hydroxyl radicals generated by their reaction with benzene to produce phenol was performed through UV-Vis spectrophotometry (UV-Vis) and high perfor- mance liquid chromatography (HPLC). ...
Choosing the right geomembrane and geomembrane manufacturer for your construction project involves several considerations, including geomembrane application, environmental conditions and the specific requirements of the geomembrane project. Geomemebranes are geosynthetic materials used in civil engineering, usually thin films made of materials such as high density polyethylene (HDPE), low density ...
The partition method essentially ‘parts’ the breath sample, and omits the first few seconds to ensure any potential high ambient levels of NO present in the breath are not measured during sampling. ...
The test process usually consists of the following basic stages:Analysis Workflow1. Sample Preparation(1) Clean all sample bottles and utensils to avoid contamination.(2) Prepare the sample solution, ensuring that the sample is within the appropriate concentration range to avoid multi-body effects or too low signal strength.(3) ...
By measuring these absorption peaks, the chemical composition of the sample can be determined.Analysis Workflow1. Sample PreparationFor the preparation of solid samples for FTIR spectroscopy, KBr is used. ...
When infrared light shines on a sample, molecules in the sample may absorb specific wavelengths of infrared light, causing changes in their internal vibrational energy levels. ...
Understanding the concentration of hydrogen in steel is crucial for innovating and developing new grades of steel to meet the rising demands of advanced applications. The Temperature Programmed Desorption (TPD) method, also known as Thermal Desorption Spectrometry (TDS) or Thermal Desorption Analysis (TDA), is a foundational approach for quantifying hydrogen content in steel and other materials. ...
Understanding High Pressure Diffusers High Pressure Diffusers (HPDs) are essential for maintaining the precision of particle counts in compressed gas samples. They act as a link between the particle counter and the compressed gas line, diffusing the gas as it enters the particle counter’s sample inlet. This ensures that the pressure is controlled to ...
Understanding High Pressure Diffusers High Pressure Diffusers (HPDs) play a crucial role in ensuring the accuracy of your particle counts when dealing with compressed gas samples. These devices serve as the bridge between the particle counter and the compressed gas line – diffusing the gas as it enters the particle counter sample inlet so the pressure is ...
In medical applications, NDIR gas sensors emit infrared light through a sample chamber containing the target gas, including carbon dioxide (CO2), methane (CH4) and carbon monoxide (CO). ...
It explains the system’s components, such as sampling mechanisms and detection chambers, and methods like light scattering for analyzing dust concentration. ...
NDIR sensors operate on the principle of molecules absorbing specific wavelengths of infrared light. Air samples are collected in a tube and subsequently analyzed under a source of light. ...

Hydrogen’s unique behaviour in metals, particularly in steels, plays a pivotal role in various scientific and industrial applications. Notably, hydrogen’s influence on phenomena like hydrogen embrittlement and tritium retention in fusion reactor wall tiles underscores the necessity for accurate and sensitive detection and analysis methods. To cater to this need, Hiden Analytical ...
A heated water bath is a piece of lab equipment used to heat samples or reactions to a set temperature. A temperature controlled water bath is useful in any laboratory for heating reactions, thawing samples, maintaining sample temperature or incubation. ...
Each model benefits from high and low temperature alarms to keep your samples secure and alert you to any issues as soon as possible, with easily visible indicators. The easy door closing feature allows the user to remove samples without worrying about the door being open for longer than necessary. An inner glass safety door not only improves insulation of the ...
Additionally, there is a much smaller safety margin in the event that LN2 refill could not be performed.Liquid Nitrogen (LN2) Storage DewarDry cryogenic storage is where there is complete separation of samples and the LN2. Typically, the LN2 is contained within a ‘jacket’ which surrounds a sealed inner chamber that contain the samples, which ...
Researchers can use these chromatograms to further break down the chemical properties of the sample mixture. The ratio of the peak size is related to the amount of substance in the sample. Area under a mountain peak is used to determine the sample size. For example, to determine a component in a sample, a standard ...
