to a 2-mL autosampler vial with a 250-µL vial insert, and injected neat into the GC. Instrumentation Analysis of bourbon whiskey was completed on an 8890 GC with a flame ionization detector (FID). A split/splitless inlet was used in split mode. Helium carrier gas was used in constant flow mode. Table 1 provides detailed method

The dimensions for 12x32mm vials are standard between manufacturers but the length of the neck and width/shape of the vial shoulder may vary. 12x32mm microvials have the same outer dimensions but the inside of the vial may be tapered to reduce volume or contain a fused insert. 12x32mm high recovery vials will have an internal conical bottom that allows for maximum sample recovery.

The equilibrium for gas chromatography is partitioning, and the components of the sample will partition (i.e. distribute) between the two phases: the stationary phase and the mobile phase.Compounds that have greater affinity for the stationary phase spend more time in the column and thus elute later and have a longer retention time (t R) than samples that have higher affinity for the mobile phase.

For Detector end: Check the gas flow by dipping the detector end of the column into a vial of non-toxic solvent (Water: IPA, 50:50) and check for carrier gas bubbles. Install the detector end of the column into the detector port making sure to insert it at the appropriate distance and follow the remaining procedure as per step-7.2.2.2 to 7.2.2.3.

The vial puck allows users to easily index the vial to begin sample agitation. Insert the holder into the sampling stand, passing the needle through the septum that seals the sample vial. Depress the plunger down to expose the fiber to the sample liquid or headspace above the sample.

The most commonly used vials are 9mm, 12x32mm screw thread vials. A 12x32mm vial is also known as 1.5mL, 1.8mL, and 2.0mL vials by different manufacturers. Microsampling options include using a one-piece vial with fused insert molded into the vial, or using a separate insert placed into a vial.

Interlock limited volume vials offer the performance and convenience of a one-piece microvial for a fraction of the cost. A 300 µL insert is fused into a 12 x 32 mm clear or amber glass vial. This one-piece design reduces the potential for contamination.
