Ultrapure water for trace elemental analysis
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.
Milli-Q® IQ Element: Analytical-grade water for single-ppt and sub-ppt detection levels
Laboratories performing trace analyses need a reliable source of ultrapure water with consistently low elemental concentrations. When combined with a Milli-Q® IQ 7000 or Milli-Q® IQ 7003/05/10/15 water purification system, the Milli-Q® IQ Element purification and dispensing unit delivers analytical-grade ultrapure water that is suitable for trace and ultra-trace elemental analyses, including ICP-MS, GF-AAS and trace IC.
The Milli-Q® IQ Element unit dispenses water at your point of use, which is confirmed to contain extremely low levels of elemental contaminants, from single-ppt to sub-ppt. Independent laboratories specialized in ultra-trace elemental analyses have verified the unit’s water quality.
Seamless, contaminant-free integration into your cleanroom environment
The compact Milli-Q® IQ Element unit is designed to be easily integrated into your laboratory space and installed inline of a Milli-Q® IQ 7 series water purification system. Its compact dispensing unit can be placed directly at your point of use, in your cleanroom environment or laminar flow hood, with no risk of contamination.
