. We offer five types of detectors. Each one is specifically designed to fit your needs.

√ Flame Ionization Detector (FID): Used for analyzing organic compound requiring high sensitivity.
√ Thermal Conductivity Detector (TCD): Used for analyzing ambient temperature gases, water, and small hydrocarbon compounds.
√ Flame Photometric Detector (FPD): Used for analyzing sulfurous or phosphorous compounds.
√ Electron Capture Detector (ECD): Used for detecting pesticides or chlorides through Electron Capture
√ Nitrogen-Phosphorus Detector (NPD): Used for trace analysis of nitrides or phosphides
