Type I Ultrapure vs. Type II Laboratory Water
Understanding the analytical distinction between Type I polishing grades and Type II general laboratory water to ensure proper application matching and prevent experimental contamination.
Type I Ultrapure Water
Milli-Q Type 1Type I water is the highest purity grade, treated to remove dissolved ions, organic contaminants, bacteria, and particulates. Required for critical analytical applications where impurities interfere with quantification or instrument sensitivity.
Target Applications:
Type II Laboratory Water
Milli-Q Type 2Type II water is purified by reverse osmosis, electrodeionization (EDI), or distillation. It provides reliable, consistent water for general laboratory processes, reagent preparation, and serves as optimal feed water for Type I polishing systems.
Target Applications:
Target Applications & Laboratory Workflows
Selecting the right grade of water prevents ghost peaks, baseline drift, ion suppression, and false positive detections in specialized instrumentation.
Liquid Chromatography (HPLC, UHPLC, LC-MS)
Ultra-low organic impurities to prevent baseline noise, ghost peaks in gradient elution, and ion suppression in electrospray mass spectrometers.
Trace & Elemental Analysis (ICP-MS)
Extremely low sub-ppb/ppt background of alkali, alkaline earth, and heavy transition metals to guarantee low limits of quantification (LOQ).
Molecular Biology & Genomics
Sterile-filtered water verified free of DNase, RNase, and endotoxins to protect sensitive RNA/DNA samples and enzymatic PCR reactions.
Gas Chromatography (GC & GC-MS)
Strictly controlled volatile and semi-volatile organic content for purge-and-trap, headspace analysis, and organic trace extraction.
Spectroscopy & Electrophoresis
High UV transmission down to 190 nm, low fluorescence background, and zero particulate interference for UV-Vis and capillary electrophoresis (HPCE).
General Laboratory & System Feed
Standardized high-purity water for preparation of buffers, analytical reagents, microbiological culture media, and polishing system feed.
