DI Water System
Description Applications
Sophisticated high-purity deionized (DI) water feed system that processes DI water from building deionizing beds into a pump-driven polishing loop with dedicated UV lamp. This is fed to two Millipore Milli-Q Element ultrahigh-purity water systems resulting in DI water that is essentially free of all inorganic and organic impurities.
  • - Analysis of trace impurities in samples requiring dilution with DI water.
  • - Used for IC, ICP-MS, ICP-OES, AAS and TOC analyses.

  • - M3 Building Deionizing Beds: 1-12 MOhm DI water
  • - M3/2158 Polishing Loop: 12-16 MOhm DI water
  • - Milli-Q Element DI Water: > 18 MOhm / < 1 ppm TOC DI Water

Casio EXLIM EX-F1 High Speed Camera
Description Applications
The EXLIM can operate as a single shoot or high speed digital camera. The shooting rate is variable for the 60 images, ranging from one image per second for a full minute (one image per second) to 60 fps. All of this means that the EX-F1 allows burst shooting at speeds faster than those possible with a single reflex camera, and beautiful images of each moment of high-speed action as it occurs.
