For analysis of compounds which show interactions with untreated glass surfaces, it may be necessary to use a deactivated glass vial. The effect of adsorption is most apparent when dealing with very low concentrations of the sample. It is likely that this effect will only be identified during calibration. Analytical results will show poor reproducibility and linearity for active samples while non-adsorbing species show good results.
Inert glass products can be found in Performance level 3, and include silanized glass and GOLD-grade technology deactivated glass.
The micro inserts have a small total volume capacity of <400 µL and can be classified as either Polyspring, conical, or flat-bottom within the SureSTART Collection. Micro inserts are placed and sealed inside a vial so they can be used in conventional autosampler racks. The smaller 6 mm diameter of the insert gives better sample recovery than a routine flat based vial with conical inserts being most effective with residual volumes of 1-2 µL. Many are held in place by a Polyspring, which cushions and centers the insert.
