To accommodate the decreased sample volume, chromatographers need to use HPLC vials which have inserts in them (as in Figure 1) so that small samples can be reproducibly injected into an HPLC system. Even though the amount of sample available for chromatography is reduced, the sample still needs to be filtered to ensure that it is particle-free
Screw-top vials also come in different sizes, with vial caps made of either aluminum for crimp seals or plastic. Amber glass vials are available in 2-60 ml volume with a screw top. Inserts work in conjunction with any autosampler and fit either standard or wide openings vials.
Inserts with an outside diameter of 5mm are used with vials with standard mouth openings and the 6mm are used with wide mouth vials. The length of the insert should be flush with the neck of the vial to prevent the insert from causing the septum to bulge. Conical inserts have a tapered bottom with pulled tips and are available with or without
Alliance HT HPLC Systems. This vial delivers maximum sample capacity (~1.5 mL) with minimum residual volume. The 9 mm cap makes it ideal for use with aijiren HPLC and GC Systems. Choosing the level of certified vial should be based on the concentration of analyte. Concentration of analytes is often tied closely with the detection source used.
With thousands of combinations to choose from, DWK Life Sciences offers the largest and most diverse selection of chromatography lab vial solutions and microplates. Our ISO 9001 facility manufactures vials that meet or exceed OEM specifications for headspace, routine HPLC/GC use, plus Certified vials for LCMS/GCMS.
The purpose of the NGSP is to standardize Hemoglobin A1c test results to those of the Diabetes Control and Complications Trial (DCCT) and United Kingdom Prospective Diabetes Study (UKPDS) which established the direct relationships between HbA1c levels and outcome risks in patients with diabetes.
