Click for Large
Air Concentrator – The Custom GC Air Concentrators for both the Companion Portable GC and Series 600 GC’s are built right in. Most importantly, this provides both a compact portable sample concentrator and a shortest possible sample path. Above all, a heated valve and heated sample lines create an inert sample path. The sample trap is plumbed in a true backflush fashion. It also can be equipped with a variety of packing materials to achieve the best concentration of the compounds being analyzed. To start, a built-in vacuum pump loads the sample and a variable flow controller ensures consistent sample trapping and GC analysis. From start to finish, the entire sequence of the Air Sample Concentrator is automated through the Timeline of the DPS Control Software for the GC analysis of one sample. If needed the system can also be set up to run unattended 24/7, collecting and analyzing samples every hour, or so.

Headspace Concentrator

Headspace Concentrator – The Custom GC Headspace Concentrator for both the Companion Portable GC and Series 600 GC’s are built right in to provide the shortest possible sample path. Each Sample Vial is heated and then consistently Pressurized before loading the Sample Loop. A fixed Sample Loop ensures reproducible sampling and consistent GC analysis. In addition, the sample lines are Flushed between analyses to limit any cross-over contamination. Above all, the entire sequence of the Headspace Concentrator is automated through the Timeline sequence of the DPS GC Control Software for the GC analysis of one sample at a time.

Purge & Trap Concentrator

Purge & Trap Concentrator – The Custom GC Purge & Trap Concentrator for both the Companion Portable GC and Series 600 GC’s are built right in with Trap features similar to the Air Concentrator. At first, water samples are purged with inert gas to extract the sample compounds and load them onto the Trap. In addition, a variable flow controller regulates the Purge Gas for consistent sample trapping and GC analysis. In short, the entire sequence of the Purge & Trap Concentrator is automated through the Timeline of the DPS Control Software for the GC analysis of one sample at a time.

MicroExtractor Concentrator

MicroExtractor Concentrator – The Custom GC MicroExtractor concentrator is a exciting innovation, but only from DPS, which concentrates higher boiling compounds directly from water samples. At first, the sample vial is pressurized and the water sample is pushed through the trap at ambient temperature, where the compounds are concentrated. After that, the trap is heated and the compounds are directed to the analytical column for GC analysis. In conclusion, the entire sequence of the MicroExtractor Concentrator is automated through the Timeline of the DPS Control Software.

FCO Upgrade for Fast GC

FCO Fast BTEX for Custom GC System

The Fluidless Column Oven (FCO) is a revolutionary low mass accessory. The column is sealed inside an insulated oven, but comes in direct contact with the heater elements. Therefore, this contact allows the gradient to be transferred directly to the column. The low mass of the oven and direct heating make very fast temperature ramping possible in both the Extended Run and Classic models. In addition an integrated chiller cools the column between runs and is powerful enough to permit sub-ambient GC analysis starting as low as 20°C.

Custom GC - Detectors

BCD
Bromide Chloride Detector

BCD Detector for GC Analysis
Click for Large
BCD Overview – Above all, the BCD detector is highly selective to Bromine and Chlorine compounds. Moreover, the BCD is only available in DPS Custom GC Systems. While the BCD sensitivity to these compounds approaches the sensitivity of the radioactive ECD detector, the detector is completely non-radioactive. To start, at very high temperatures, the aluminum in the ceramic collector acts as a catalyst to cleave Bromide and Chloride ions from the molecules. The catalytic activity starts around 700°C and increases exponentially, with the temperature of the Reaction Cell. However, we limit the Reactor Cell to 1000°C for safety purposes. Finally, the negatively charged Collector Electrode attracts the resultant positively charged Molecules.

FID
Flame Ionization Detector

FID Detector for GC Analysis
Click for Large
FID Overview – The FID detector is selective to all compounds that burn, therefore it is commonly used for the analysis of hydrocarbons. At first, a precisely controlled Hydrogen and Air mixture is ignited and burns as a small flame at the end of a jet within the Detector Body. Consequently, all compounds exiting the column pass through the flame. As a result, those that are combustible ionize. After that, the negatively charged Collector Electrode attracts the positively charged Ions.

FPD
Flame Photometric Detector

FPD Detector for GC Analysis
Click for Large
FPD Overview – The FPD detector can be configured for 2 modes of operation. Firstly, a highly selective configuration for Sulfur compounds. Or secondly, a mode that is highly selective for Phosphorus compounds. To start, a precisely controlled Hydrogen and Air mixture is ignited and burns as a small flame at the end of a jet within the Detector Body. Therefore, all compounds exiting the column pass through the flame and those that are combustible ionize. After that, all excited Sulfur, or Phosphorus ions return to their ground state and emit photons. The specific wavelength filters within the detector body only let certain photons pass through to a Photo Multiplier Tube (PMT), where they are detected and amplified. The FPD produces a lot of water, which is a problem for most Portable GC´s, however the unique design of the DPS FPD detector takes care of this problem.

HID
Helium Ionization Detector

HID Detector for GC Analysis
Click for Large
HID Overview – The HID detector is a universal broad range detector, so it is highly sensitive to almost all compounds. At first, in a pure helium environment, a current flows between two electrodes creating a plasma of high energy short wavelength photons. Consequently, as the compounds exit the column they are bombarded by these photons and Ionized. Take note, that the energy of these photons are 24 eV, which is sufficient to Ionize almost all compounds. After that, the negatively charged Collector Electrode attracts the resultant positively charged Ions. The HID can be run in series with other detectors, such as a FID, PID, or BCD. The unique design of the DPS HID detector is ideal for both Series 600 Lab and Portable Custom GC Systems.

NPD
Nitrogen Phosphorus Detector

NPD Detector for GC Analysis
Click for Large
NPD Overview – The NPD detector is highly selective, but only for Nitrogen and Phosphorus containing compounds. At first, a precisely controlled Hydrogen and Air mixture surrounds the NPD bead within the detector body. Secondly, a voltage is applied to the bead to activate the surface. Finally, Nitrogen or Phosphorus compounds react with the activated surface as they exit the column creating Ions. Consequently, the negatively charged Collector Electrode attracts the resultant positively charged Ions.

PID
Photo Ionization Detector

PID Detector for GC Analysis
Click for Large
PID Overview – The PID detector is highly sensitive to hydrocarbons, but only those that are aromatic, or have double or triple bonds. To begin, the PID lamp emits 2 major wavelengths of high energy Ultraviolet light that travel through the window of the lamp. After that, the compounds exiting the column are bombarded by these UV photons and Ionized. Finally, the positively charged Ions are attracted to the negatively charged Collector Electrode and amplified. The energy of these photons averages 10.6 eV, and this is sufficient to ionize aromatic compounds, but not aliphatic compounds. Since the PID is non-destructive, the PID detector is commonly used in series with other detectors. For instance, in DPS Custom GC Systems the PID is used in series with both the BCD and FID detectors.

TID
Thermo Ionic Detector

TID Detector for GC Analysis
Click for Large
TID Overview – In short, the TID detector is highly selective to Amines and Nitroaromatic compounds commonly found in explosives. At first, a precisely controlled Nitrogen, or Air mixture surrounds the TID bead within the detector body.  Secondly, a Voltage is applied to the bead to activate the surface. After that, Amines and Nitroaromatic compounds react with the activated surface as they exit the column creating Ions. Therefore, the negatively charged Collector Electrode attracts the resultant positively charged Ions.
