SPME is a widely used technique for the extraction and concentration of volatile compounds from a wide range of samples. It is particularly useful in the food, flavor and beverage industry. GERSTEL is the leading provider of automation for SPME and has taken it one step further than everyone else by now offering a Multi-Fiber Exchange Option, that allows a single sample to be analyzed using ...
Multiple sorbent coatings available in the forms of C18 and PDMS/DVB. • 10 mm of exposed fiber to expose to your sample matrix. • SPME fibers extract targeted analytes concentrating them while leaving behind salts and ionization inhibiting ...

The high puncture tolerance makes these septa ideal for autosamplers as well as users of solid phase microextraction (SPME). Figure 2 shows examples of our molded septa with and without injection holes. ...
For laboratories that require high sample throughput and the ability to conduct pre-injection sample processing, Combi PAL is the ideal choice.Versatile introduction methods and injection modes Liquid, headspace, Solid Phase MicroExtraction (SPME) and In-Tube EXtraction (ITEX) injections are all possible. ...

All rights reserved.Practical Considerations• Syringes– Large enough so it is not filled to capacity– Extract/sample should occupy at least 10% of the syringe volume– Use gas tight design for gas phase samples• Reproducibility– Use an autosampler when able– For manual injections…– Use a Chaney adapter– Be smooth and rapid• Inlet Liner– Use the correct design for the injection ...
Variable vial penetration depth allows to extract the compounds in liquid samples itself or in the headspace area above liquid/solid samples. After the compounds are thermally desorbed in the hot GC injector, the fiber may be fully cleaned again in a special heated and purged Fiber Conditioning Station.8*Solid Phase ...
When a bonded phase is not available, such as for the high polarity phases, look for a stabilized phase. ...
We therefore aim for a SETAC platform where scientists can share their views on topics that are specifically relevant for ionic species, e.g. the mechanisms underlying ion-exchange processes and the relative importance of hydrophobic interactions, interactions with inorganic sediment and soil phases and cellular uptake mechanisms. B03 - Fate and biogeochemistry of metals ...
