Gas Standards Generator offers NIST traceable concentrations.

Model 491M-B-T creates trace concentration standards for mercury and mercury compounds. Standards are prepared dynamically by mixing small flow of mercury vapor with larger flow of clean dilution gas. Held at constant temperature between 80-120°C, Trace Source(TM) permeation tubes dispense minute flow of mercury vapor. Concentrations from below 500 pptv to over 100 ppbv are possible using single...

Generator meets parts per trillion gas standards.

Model 491M/B/SD blends precisely known gas standards with parts-per-trillion (ppt) analyte concentrations. System uses 2 independent stages of dilution to achieve ppt concentrations, allowing standards to be created from analyte flow rates above 10 ml/min with total dilution gas flow of less than 20 l/min. System can make additions to the dilution gas to compensate for unknown contamination....

Backup System prevents unexpected gas outages.

Model 58BGS provides continuous backup for any type of gas generator. It automatically switches to backup supply of cylinder gas when primary gas supply drops below preset value. Process automatically reverses when gas supplied by generator returns to above changeover value. Stainless steel and brass versions incorporate 2-stage regulator, line regulator, and in-line check valves. Preset pressure...
