The CUSTODION™ SPME Syringes are a series of novel solid phase micro extraction (SPME) based sample collection and injection devices.
Sample introduction is quick and easy with the CUSTODION®
solid phase microextraction (SPME) syringe. Target analytes are rapidly trapped and concentrated on the active coated surface of the SPME fiber. The CUSTODION®
syringe can be used on any GC or GC-MS instrument.
Target analytes in air, headspace, liquid or dissolved solid samples are quickly trapped on the active coated surface of the SPME fiber, which is mounted inside the easy-to-operate syringe type holder. The push button trigger on top of the syringe enables the SPME fiber to be quickly extended for sampling and then quickly withdrawn into a protective metal sheath after sampling and while being inserted into the injection port of a GC or GC-MS. The fiber can then be extended by pushing the trigger button while in the heated injection port for thermal desorption into the GC column and analysis of the collected sample.
The CUSTODION SPME syringes are designed for easy single-handed operation in protective gloves. The push button trigger mechanism on top of the syringe body is easy to use and either extends the fiber for sampling and sample injection or retracts the fiber for protection between sampling and injection. The button is color-coded for easy viewing of the SPME fiber’s position. Sample collection is easy and is accomplished by exposing the SPME fiber to the sample for as little as a few seconds to as long as several minutes.
A unique feature of the Torion CUSTODION SPME syringes is an electronic chip on the PC board that is used to store sample metadata, such as sampling location, date, time, etc. This information increases the reliability of the device for sample tracking purposes. The device reliably collects samples, stores sample data, and in the case of the GUARDION-7 GC-TMS triggers the instrument to start upon injection of the sample.
SPME has gained wide spread acceptance as the technique of preference for many applications including flavors and fragrances, forensics and toxicology, environmental and biological matrices, and product testing to mention a few.
