DPS Forensic GC Systems - Application Notes


    Each of these Forensic Applications can be analyzed using one of the Custom GC configurations of the Series 600 Lab GC. However, all of them can also be analyzed using the Companion 1, or the Companion 2 Portable GC Systems.  Best of all, each of these Custom GC Systems gives the same great results. So, whether your analyzing in the Lab, or in the factory, or out in the field, you can rest assured that your Forensic results will always be consistent.

Anesthetics

    Government agencies generally recommend that no worker should be exposed to concentrations greater than 2ppm of any halogenated anesthetic agent over a period of time. There are no documented adverse effects of chronic exposure to Waste Anesthetic Gases (WAG’s) in the workplace. Although results of some studies suggest a link between exposures to halogenated anesthetics and increased health problems. Precautions include adequate ventilation in the operating room, a scavenging system, and work practices to minimize leaks. We designed the Forensic DPS Anesthetics GC Systems with safety in mind to check the purity of the concentrated anesthetic, monitor workplace concentrations, or analyze sample concentrations during anesthesia. The latest designed high resolution column and the sensitive FID detector does the hard work for you. We have added a built-in Headspace Concentrator for your convenience. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC Systems for analyses right where the samples are taken. The fast heating and rapid cooling column oven in every DPS GC vastly increases your sample throughput. The fully integrated Anesthetic GC Analyzer Systems are small and lightweight and all Forensic DPS systems are modular for expandability, upgrades, and easy service.
Example Compounds:
Isoflurane
Enflurane
Halothane
Methoxyflurane
etc.

Arson Accelerants

     An accelerant is a fuel that causes a fire to burn hotter, spread more quickly, or be unusually difficult to extinguish. Investigators can prove that a fire was set intentionally by finding an accelerant, such as gasoline, kerosene, turpentine, or diesel fuel at the scene of a fire. Various techniques such as DFLEX strips, headspace concentration, or sample extraction can be used to detect accelerants at a fire scene. Although the sampling techniques vary we configured the Forensic DPS Arson Accelerants GC Systems for multiple sampling techniques. An extract can be directly injected by hand, or a debris sample can be placed in a vial and automatically heated and injected using our built-in Headspace Concentrator. In either case, a high resolution column and the sensitive FID detector quickly identify the accelerant fingerprint. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC Systems for analyses right where the samples are taken. The fully integrated Arson Accelerants GC Analyzer Systems are small and lightweight and all Forensic DPS systems are modular for expandability, upgrades, and easy service.
Example Compounds:
Gasoline
Kerosene
Turpentine
Diesel

Blood Alcohol

     The analysis of ethanol in blood, breath, and urine are the highest volume tests performed in forensic labs today. In the past these biological samples have been injected directly on the analytical columns causing injection port build up and column plugging. To vastly reduce the sample preparation time and GC System maintenance headaches, headspace methods have been adopted and verified. We configured the DPS Blood Alcohol GC Systems with a built-in Headspace Concentrator, the latest designed high resolution capillary column, and the sensitive FID detector to quickly detect ethanol and the other major constituents in less than 3 minutes. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC Systems for analyses right where the samples are taken. The fully integrated Blood Alcohol GC Analyzer Systems are small and lightweight and all Forensic DPS systems are modular for expandability, upgrades, and easy service.
Example Compounds:
Methanol
Acetaldehyde
Ethanol
Isopropanol
Acetone
n-Propanol

Drugs of Abuse

     Drug screening of employees is increasing around the world. Many employers have been forced to administer programs due to the high costs of drug related work incidents. Additionally, a resent study had shown that about two-thirds of patient visits to hospital emergency rooms for drug abuse would have been misdiagnosed without lab testing. Many times doctors and are not sure what patients have taken, and the same holds true for many DOA cases. The only way to determine what a patient may have taken is by drug testing. We configured the DPS Drugs of Abuse GC Systems with the latest designed high resolution capillary column and the sensitive FID detector to quickly detect these compounds. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC Systems for analyses right where the samples are taken. The fast heating and rapid cooling column oven in every DPS GC vastly increases your sample throughput. The fully integrated Drugs of Abuse GC Analyzer Systems are small and lightweight and all Forensic DPS systems are modular for expandability, upgrades, and easy service.
Example Compounds:
Amphetamine
Methamphetamine
Nicotine 
Cotinine
Caffeine
Benzphetamine
Ketamine
Phenylcyclidine
Methadone
Cocaine
Codeine
Scopolamine
Alprazolam

Forensic Solvents

     This broader group of organic solvents contains many of the compounds identified by the more specifically configured Blood Alcohol and Inhalants GC Systems. These solvents can be major components, or impurities in household cleaners, paints, glues, and many other readily available products, as well as solvents found in biological fluids. Since you are not quite sure what you are going to find, or what concentration it may be, we have configured the DPS Forensic Solvents GC Systems with the highest resolution general purpose column available and the sensitive FID detector. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC Systems for analyses right where the samples are taken. The fast heating and rapid cooling column oven in every DPS GC vastly increases your sample throughput. The fully integrated Forensic Solvents GC Analyzer Systems are small and lightweight and all Forensic DPS systems are modular for expandability, upgrades, and easy service.
Example Compounds:
Methanol
Ethanol
Acetone
Acetonitrile
Isopropanol
Ether
tert-Butanol
Methylene Chloride
n-Propanol
Methyl Ethyl Ketone

Ethyl Acetate
Chloroform
Tetrahydrofuran
Benzene

Inhalants

     There are more than 1000 ordinary household products that may be abused via inhalation, such as hair spray, glue/adhesives, gasoline, paint, solvents, marker pens, correction fluid, butane lighter fluid, propane gas, cooking sprays, and household cleaners. These products are easy to obtain, inexpensive, and contain volatile substances that the user perceives as being free of toxic components. The availability and low cost of these products make them more accessible to children than tobacco, alcohol, or drugs. Consequently, inhalant abuse is on the rise, especially among young people. The Forensic DPS Inhalants GC Systems are configured with the latest designed high resolution column and the sensitive FID detector to quickly detect these compounds. The Series 600 GC is for analyses in the lab, or use the Portable Companion 1 GC System for analyses right where the samples are taken. The fast heating and rapid cooling column oven in every DPS GC vastly increases your sample throughput. The fully integrated Inhalants GC Analyzer Systems are small and lightweight and all Forensic DPS systems are modular for expandability, upgrades, and easy service.
