Waters offers a broad range of vials, each one is held to tight dimensional tolerances and the certified products have cleanliness measured by LC and MS.
LC/GC Certified vials are tested by LC/UV for residues of chemicals used in processing and packaging vials. The septa are tested by headspace GC to ensure low levels of low molecular weight polymer. These vials are suited for analyte concentration in the µg/mL concentration; typically detectors like UV and RI. LC/MS Certified Vials are tested by MS scans from 250 to 1000 m/z with specifications set on the total ion count and presence of clusters in the high mass range. These vials are suited for analyte concentrations in the 100’s ng/mL concentration.
TruView LCMS Certified Vials are manufactured by a proprietary process that reduces analyte adsorption. The testing includes dimensions, LC/UV and MS cleanliness. In addition there is a high recovery of analyte test run at 1 ng/mL concentration using UPLC/MS/MS (MRM) and yield little adsorption. These vials exhibit the lowest adsorption of autosampler vials on the market.
Waters also offers a selection of glass sample vials and plastic sample vials that fit most manufacturers’ instruments. Two of the most popular uses are as HPLC vials and GC vials. These chromatography vials can be used as sample storage vials by adding a solid caps with liner.
