Milli-Q® IQ Element
Technological advances in sensitive analytical techniques, such as inductively coupled plasma mass spectrometry (ICP-MS), graphite-furnace atomic absorption spectroscopy (GF-AAS) and trace ion chromatography (IC), allow us to detect and measure elements
at ppt and sub-ppt levels. These trace and ultra-trace detection levels are key for sensitive applications in such diverse fields as environmental testing, pharmaceutical analyses, forensic science, and the food and beverage industry.
Low detection
levels mean that special care must be taken to avoid trace contamination, which can impact experimental results. Contaminants may arise from the reagents, instrumentation, operators, lab environment and any sample containers used.
This is equally
true for ultrapure water used in the analytical process. Due to the dissolution and dilution processes required in sample preparation, high-purity water typically constitutes over 90% of a sample analyzed by these sensitive techniques. High-purity water
is also used for cleaning sample containers, washing plastics, and preparing blanks and standard solutions.
