CUSTODION™ SPME Syringes
The CUSTODION SPME Syringes are a series of novel solid phase micro extraction (SPME) based sample collection and injection devices. Sampling and gas chromatographic (GC) injections are Quick, Easy and Reliable with the new CUSTODION-10, CUSTODION-11, and CUSTODION-12 SPME syringes. CUSTODION SPME Syringes are color coded for easy recognition of syringe type. The CUSTODION Syringes are an ideal tool for fast, easy sample
collection, preparation, and GC injection. These devices can be used for:
- Field sampling
- Sample screening
- Head space analysis
- Chain-of-custody tracking
- Product quality testing
- In-laboratory applications
SPME Technology
Solid phase mirco extraction, or SPME, is an innovative technology that is quick, easy, and reliable. SPME is a solvent-free extraction technique that combines extraction, collection, and concentration of analytes present in gas, liquid, and dissolved solid samples. The fiber's coating removes chemical compounds from the sample matrix by absorption in the case of liquid polymer coatings or by adsorption in the case of solid coatings. SPME technology provides the user with quick and convenient sampling and concentration in a single step. After sample collection, the SPME fiber is inserted directly into the heated injection port of a gas chromatograph (GC) for thermal desorption, separation, and detection. CUSTODION SPME Syringes can be reliably used for on-site field sampling or in-laboratory applications.
SPME has gained widespread acceptance as the preferred sampling technique for many applications such as:
- Pesticide residue analysis in water, soil, and air
- Food and beverage testing foradulterants or contaminants
- Consumer product sampling for flavor and fragrance constituents
- Forensic analysis of illicit drugs, precursors and metabolites
- Security testing for explosives and related residues
- Field military operations for detection of chemical warfare agents
Quick
Target analytes in air, headspace, liquid or dissolved solid samples are quickly trapped by the active coated surface of the SPME fiber, which is mounted inside an easy-to-operate syringe holder. The CUSTODION SPME Syringes quickly collects samples, and stores sample metadata.
Easy
The CUSTODION SPME Syringes are designed for easy single-handed operation in protective gloves. The push button trigger is color-coded for easy viewing of the SPME fiber position. Sample collection is easily accomplished by exposing the SPME fiber to the sample for as little as a few seconds to as long as several minutes.
Reliable
A unique feature of the Torion CUSTODION SPME Syringes is an electronic microchip that is used to store sample metadata, which increases the reliability of sample tracking. In the case of the GUARDION-7GC-TMS,the CUSTODION Syringes also trigger the instrument to start upon injection of the sample.
