Application Quick Reference Guide

Particle Analyzers
Particle analysis is used in many applications ranging from
sub-micron measurements in water for micro-electronics
The absence of contaminating particles in the water is
key. Water purity itself is not usually critical. 0.2 um
filtration is often adequate but this can be extended to
0.05um or lower. Type II pure water is recommended for
general sensitivity and Type I ultrapure water should be
used for more critical sensitivity.

Polymerase Chain Reaction (PCR)
PCR is a technique in molecular biology to amplify a single
or few copies of a piece of DNA by several orders of
magnitude, generating thousands to millions of copies of a
particular DNA sequence.
PCR and related PCR-based techniques, including
quantitative PCR and reverse transcriptase PCR, require
nuclease-free and endotoxin-free water to avoid the
degradation of the nucleic acid. Water should also be
free of specific ions, organics and bacteria. Apyrogenic
Type I ultrapure water is essential.
