Gas Chromatograph Detectors

Gas Chromatographs

Gas Chromatograph Detectors

Up to 4, 5, or 6 Detectors can be Installed on One GC
Several Detectors can be Run in Series for Multiple Chromatograms from One Injection
No one has more Detectors or Configurations than Buck!

Each detector is equipped with a thermostatted heater block for temperature stability, internal amplifier electronics, and electronic pressure controlled (EPC) support gases, such as hydrogen and air for the FID detector. All detectors require factory installation. Prices listed are for the detector mounted on a Buck GC chassis.

Part Number	Description	Price	Quantity
Catalytic Combustion Detector (CCD)	About as sensitive as a TCD, the Catalytic Combustion Detector has the hydrocarbon selectivity of an FID, plus the ability to operate on air alone. Because the CCD requires no compressed gases like hydrogen or helium, it can be used in Buck's Gasless GCs	$1,229.00
Dry Electrolytic Conductivity Detector (DELCD)	The Dry Electrolytic Conductivity Detector is useful for low-level detection of chlorinated and brominated solvents in environmental samples and other trace analyses. In the picture above, a DELCD is mounted next to FID and PID detectors on a Buck GC. The	$4,119.00
Electron Capture Detector (ECD)	The ECD detects electronegative compounds, especially chlorinated, fluorinated or brominated molecules such as carbon tetrachloride, bromoform, PCBs and pesticides such as DDT. The ECD offers extreme sensitivity (parts per trillion for SF6).	$6,179.00
FID/DELCD Combination Detector	The FID/DELCD is one of the most useful detector combinations because it allows the operator to reliably identify hydrocarbon peaks detected by the FID as halogenated or not.	$5,149.00
Flame Ionization Detector (FID)	The FID responds to any molecule with a carbon-hydrogen bond, but not at all, or poorly, to compounds such as H2S, CCl4 or NH3. The FID response is very stable from day to day, and is not susceptible to contamination from dirty samples or column bleed.	$2,059.00
Flame Photometric Detector (FPD)	The Flame Photometric Detector can detect sulfur compounds, such as H2S or SO2, down to about 200 ppb and phosphorus compounds to 10 ppb.	$4,119.00
Helium Ionization Detector (HID)	The Helium Ionization Detector is a "universal" detector which responds to all molecules except neon. The HID is particularly useful for volatile inorganics like NOx, CO, CO2, O2, N2 and H2 which do not respond on the FID or other detectors.	$3,599.00
Nitrogen-Phosphorus Detector (NPD)	The Nitrogen-Phosphorus Detector responds to nitrogen-phosphorus compounds about 100,000 times more strongly than normal hydrocarbons. Due to this high degree of selectivity, the NPD is commonly used to detect pesticides, herbicides, and drugs of abuse.	$3,089.00
Photo Ionization Detector (PID)	Use of the Photo Ionization Detector is mandated in several EPA methods (8021, TO-14, etc.) because of its sensitivity and selectivity. Detection limits for aromatics are in the low picogram (ppb) range.	$3,599.00
Reduction Gas Detector (RGD)	The Buck reduction gas detector is sensitive to volatile reducing compounds down to the ppb level, and is often used to detect atmospheric carbon monoxide and hydrogen.	$6,179.00
Thermal Conductivity Detector (TCD)	Because it detects all molecules, the Thermal Conductivity Detector is commonly used for fixed gas analysis (O2, N2, CO, CO2, H2S, NO, etc.) where the target analytes do not respond well on other, more sensitive detectors. The TCD can detect concentration	$2,059.00
Thermionic Ionization Detector (TID)	The Thermionic Ionization Detector is similar in design to the FID and NPD. The electrically heated thermionic bead (TID bead) is positioned so that the column effluent contacts the hot bead surface. Analyte molecules containing NO2 (nitro) functional gro	$3,089.00
