Quality Range

These products were developed for a broader and more routine set of applications, than those of the Premium or Industry Specific ranges.  Although they are produced to a lower specification than the premium range they can be used on a wide variety of instruments, particularly where the higher specification Premium range products are not required.  This quality range of standards represents excellent value for money.

  • Extensive range (5 ppm - 5000 ppm)
  • Represents excellent value for money.
  • Mixed TOC and TIC standards available as a normal part of the range.
  • Presented in special twin neck bottles (all values above 50 ppm, 500ml size) which prevents product contamination, evaporation or interference.
  • All values below 50 ppm are packed in specially cleaned and leached amber glass bottles.
