Fast and highly accurate analyzer system was needed for ethanol calibration gas standards. Precisive`s OXS-3100-HC configured for ethanol gas was selected due to its sub-ppm repeatability and high stability.
Environics® Ambient Monitor Calibrator with Ozone Generators facilitate dynamic calibration of ambient air analyzers. These instruments automatically perform zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, O3, hydrocarbons and other gases of interest. All ozone generators are factory calibrated using a NIST traceable ozone standard. The Series 6100, Series 6103 and Series 9100 all meet or exceed U.S. Environmental Protection Agency requirements.
The gas generators for calibration based on the use of “Method of Permeation Tubes.”. The permeation tubes are sealed capsules containing a small amount of the component that is in contact with a permeable membrane stable. The permeation through the membrane produces a vapor of the compound of the component of small quantity, very stable as a stream in time. This permeate stream by mixing with a dilution gas controlled and precise (for example nitrogen) creates a mixture in track at the desired...
A safe laboratory environment requires an
effective method for clearing toxic material from fume hoods. Since all handling of toxic
materials is completed in these hoods, it is
critical to have a procedure to evaluate their
operation to assure adequate protection for
laboratory workers. The InfraRan Specific
Vapor Analyzer, factory calibrated for SF6, is an ideal instrument for measuring fume hood
efficiency in accordance with ASHRAE and
other standards. Manufacturers identify the flow
dynamics (factors that...
CIC Photonics’ extensive experience with gas analysis has also included what the industry refers to as Specialty Gases, as distinguished from Semi Gases, Electronic Specialty Gases, and Industrial Gases. Specialty Gases are high purity gases used across many applications by researchers, by government agencies, and by commercial businesses. Included among these users and applications are: hospitals for medical gases; environmental labs and testing companies for blends of protocol gas mixtures; calibration gases;...
The Adsorbent Tube Injector System (ATIS) was developed at Supelco® by R&D Scientists, as a tool to assist in our comprehensive adsorbent research for thermal desorption tubes. The ATIS provides an efficient means of transferring calibration standards in either the gas or liquid phase onto the adsorbent packed tubes.
The ATIS employs the technique of flash vaporization to vaporize the sample in a continuous flow of inert gas; the inert gas carries the sample to the tube. The sample pathway of the ATIS is construct...
