If the top ring rests three lines below the top line on the side of the syringe there are 0.3 mL of liquid in the syringe (0 +0.3 = 0.3). If it rests one line below the 2.5 mark, there are 2.6 mL of liquid in the syringe (2.5 + 0.1 = 2.6). If it rests three lines below the 1.5

After washing a finger with tap water for 15 s and waiting 2 min for drying, 70 µL aqueous ethanol solution in a small vial (0.6 mL) was used to sample for several minutes. Then 3 µL of the aliquot was used for GC/MS analysis of caffeine.

This paper demonstrated an in situ headspace gas chromatography (GC) technique for monitoring bacterial growth using a commercial GC system with a multiple headspace extraction (sampling) mode. The technique was based on measuring the carbon dioxide mass in the headspace of a closed sample vial during the bacteria growth. A mathematic equation was derived in order to calculate the integrated

However, since the vial septum is pierced to deliver the reagent into the vial, it is possible to see some loss of volatile products over time as the vial sits in the tray awaiting analysis. In this case, it is often preferred to prepare the derivative ‘just in time’ so that every sample vial is treated identically and injected at the same time after derivatization is complete.
