My flashlight/timer/security light/power strip isn’t working, can you help me fix it?
There is a different company by the name of Defiant. We produce gas chromatography instruments and accessories, not flashlights. Please contact the company you purchased your flashlight/timer/security light/power strip from.
What is the difference between the Portable Gas Diluter and the BASS-100™ Gas Diluter?
The Portable Gas Diluter uses ambient air as the dilution gas and was designed for field use, with dilution ranges of 200:1. The Portable Gas Diluter must be manually adjusted to a desired concentration. The BASS-100™ Gas Diluter has a seamless interface with the Ellvin™ software, so it can automatically generate data for a calibration.
What is the difference between the Portable Gas Diluter and the Inline Diluter?
The Portable Gas Diluter is used to calibrate the FROG or TOCAM™. The portable gas diluter enables the user to mix various known concentrations from a single calibration gas cylinder. An internal compressor supplies the dilution gas in the Portable Gas Diluter, or it can be connected to a supply tank of dilution gas. The
What is the difference between the FROG and the VOCAM™?
The main difference is that the FROG™ may be used for soil, water or air sampling. The VOCAM™ may only be used for air sampling, and is primarily for distributed, fixed, or perimeter monitoring. The VOCAM™ has a heated PID to keep the PID lamp cleaner for longer periods of time. In addition, VOCAM™ has
Can I use the FROG to analyze for a certain compound?
The FROG is capable of detecting many different volatile organic compounds (VOCs). The majority of the FROG applications are for BTEX (Benzene, Toluene, Ethylbenzene and Xylenes), Chlorinated Alkenes (cis-1,2-Dichloroethene, trans-1,2-Dichloroethene, Trichloroethene, and Tetrachloroethene), and Naphthalene. However, the FROG can be used for other applications. Please reference our Application Notes page to see other applications or
