Model SAM GC-600 -Chemical Hazard Monitor
The SAM GC-600 Chemical Hazards Monitor is a high-performance analyzer that is based on gas chromatograph technology. It was developed specifically for continuous chemical hazards monitoring, and is used where highly toxic or carcinogenic substances may be present in the production-plant air or in the workplace. Based on its high level of selectivity and sensitivity, as well as its low detection and alarm limits, the SAM GC-600 is a reliable, robust monitor for hazardous substance exposure in the ppb to ppt range. It not only offers the reliability you need, it can also help you to optimize your production times, by detection.
The heart of the SAM GC-600 Chemical Hazards Monitor is a gas chromatograph equipped with an accumulation module (A). The air that is to be analyzed is continuously drawn in at all sampling points by means of two pumps (P) and - depending on the measuring path selected - passes through a multiposition valve (V) and the adsorbent-containing accumulation module. Here, all substances not normally found in air are first adsorbed, then thermally desorbed, separated from each other chro-matographically, and then detected (D). Finally, the software (PC) calculates the substance concentrations from the chroma-tograms and manages all the functions of the SAM GC-600. This controller is based on a PC, running under the Windows® operating system. The software, which was especially developed for this unit, allows all measurement results to be managed, archived, and evaluated statistically, and it also allows the alarm thresholds to be set. It provides high system functionality, robust operation, and can be individually configured. In addition, digital and analog outputs permit communication with process control systems as well as remote maintenance.
Dimethyl Sulfate (DMS) and Diethyl Sulfate
Despite their toxicity, these two substances are widely used as alkylation agents. However, they can be reliably detected well below existing threshold values using the SAM GC-600 Chemical Hazards Monitor. The low detection limit (<1 ppb) enables an early alert and response before any serious threat to human health.
Bis(chloromethyl)ether (BCME)
This highly toxic substance is formed spontaneously when formaldehyde is used in the presence of hydrogen chloride (chloromethylation reaction). BCME’s workplace limit of just 1 ppb is a clear indicator of how dangerous it is. Thanks to its ability to reliably detect concentrations as low as 10 ppt, the SAM GC-600 helps to ensure the safety of your employees.
