Are your ghost peaks coming from the GC column, or

Contaminated solvent in rinse/wash vials is easy to overlook, especially if the solvent looks clean & clear, but it only takes a very small amount of contamination to cause ghost peaks. To eliminate these wash/rinse vials as the problem, empty and replace with clean solvent or even consider replacing the entire vial. Carrier Gas

Next, 5 g of beer was weighted in the same vial. The vial was immediately sealed and stored in a refrigerator (-2 °C) for 5 hours. As soon as the sample was removed from refrigerator, a 1.27 cm long and 31-gauge needle was used for vial depressurization allowing for most of CO 2 removal. A pre-equilibrium step at 45 °C for 10 minutes was applied.

What vials are typically used in GC Headspace

Headspace Vials are manufactured from Type 1 borosilie glass, available in clear or aer. 51-expansion glass is typically used for headspace vials, although better-quality headspace vials such as those from gc headspace vials price, are made of 33-expansion glass. 33 is less likely to fracture if the vial is heated (the reason quality headspace vials are made of 33- expansion).

Headspace Vials, 10ml Laboratory Sample Glass Vials Hawach

A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial .
