FPD NPD Detector screw vials

Flame Photometric Detector An FPD detects organic compounds containing sulfur or phosphorus. Samples are burned in a hydrogen/air flame producing light. An optical filter is used to make the detector specific to sulfur compounds or phosphorous compounds. The filtered light is detected using a photomultiplier tube. Sulfur generally responds to the

FID/NPD Place a septum over the column, then the column nut and ferrule. Trim the end of the column with a column cutter. Thread the column nut and column into the detector base. Insert the column all the way into the detector jet until it stops, then withdraw 1-2 mm before tightening the nut.

The Aijiren Flame Photometric Detector Plus (FPD Plus) utilizes new photomultipliers, proprietary deactivation treatments, and other design enhancements to decrease MDLs when used in sulfur or phosphorus modes. In addition, these enhancements raise the FPD Plus maximum operating temperature.

General Information The Flame Photometric Detector The dual wavelength FPD If a heated zone is assigned to the Front Det position, an "F det type mismatch" will be declared. To override this, press [Config], scroll to the Instrument line and press [Enter]. Scroll to the F det line, press [Mode/Type], and select Sig only FPD.

Parts are available for Flame Ionization Detectors (FID), Electron Capture Detectors (ECD), Thermal Conductivity Detectors (TCD), Flame Photometric Detectors (FPD), Nitrogen Phosphorus Detectors (NPD), Nitrogen Chemiluminescence Detectors (NCD) and Sulfur Chemiluminescence Detectors (SCD).

detector (NPD), flame photometric detector (FPD), Hall electrolytic conductivity detector (HECD), or a mas s spectrometer (MS). For common pesticides, high performance liquid chromatography (HPLC) coupled with an ultraviolet (UV) detector or electrochemical detector may be preferable. This method describes the use of an electron capture detector.

The Thermo Scientific™ iConnect™ Flame Photometric Detector (FPD) has an extended operating temperature range and dual wavelength capabilities to further expand its applicability. This detector is for use with Thermo Scientific™ TRACE™ 1300 and 1600 Series GC systems.

1.3 Two detectors, either FPD or NPD, can be used for the listed organophosphorus chemicals. The FPD works by measuring the emission of phosphorus- or sulfur-containing species. Detector performance is optimized by selecting the proper optical filter and adjusting the hydrogen and air flows to the flame.
