Certified Low Adsorption (LA) Vials and Kits for LC/MS

Supelco′s new Low Adsorption (LA) vials are manufactured using a process that decreases the number of hydroxyl groups on the vial′s glass surface, significantly reducing surface activity while improving analytical quantitation and minimizing pH shifts in the sample. This same process also removes unwanted surface metals such as sodium and boron that can contaminate samples and interfere with trace analysis. Unlike other methods used to decrease vial surface activity, the elimination of surface activity in LA vials is integral to the manufacturing process and is not a chemical surface treatment.

These vials and closures are designed, engineered, and manufactured for optimum performance in HPLC, GCMS, and LC/MS applications. The vials that are used become a critical part of the analysis of the sample. All of the parts of the vial system (vial, cap, and septum) can come into contact with the sample and are critical to the outcome of the analysis. The right choice for your vials is vital to ensure proper fit with the instrument.

We recommend using LA vials with MSQ polypropylene cap/PTFE silicone septa. This cap and septa combination was purposely designed for use with mass spectrometry. It shows little to no background contamination when compared to other cap and septa products in the marketplace.

Low Adsorption (LA) Vial Kits, 2 mL

Supelco′s LA vials are manufactured from Type 1 borosilicate glass and offer the benefit of maximum sample extraction without the worry of trace analytes beign adsorbed by the vial surface.

Features and Benefits
  • Maintains sample integrity during storage
  • Minimizes pH shifts in the sample
  • Reduce metal contamination in the samples
  • Compatible with most autosamplers

Low Adsorption Center Drain Vials, 1.5 mL

The CD Vial haas a unique conical interior bottom that promotes draining of the vial′s contents into the center bottom of the vial, where virtually all of it can be extracted. The conical well, located in the exact center of the vial bottom, features a smooth transition from sidewall into the well, and the bottom thickness dimension is the same in each vial.

Low Adsorption, QSertVials, 0.3 mL

The QsertVial and closure kits eliminate all the problems associated with using inserts. The rim of the fused-in insert is positioned slightly above the closure, eliminating evaporation and cross contamination. The insert is centered into the vial, 2 mm from the bottom, alllowing for consistent sample recovery and eliminating problems cuased by variation in insert depth.

Benefits
  • Higher sample recovery with either bottom loading or side loading needles (point style 2 and 5).
  • Residual dead volume can be as low as 4 μL.
  • Consistent sample recovery from vial to vial.
