 Purity Grades and Applications

Solvents
 

ACS Grade
Meets or exceeds ACS specifications. For general procedures requiring stringent quality specifications such as analytical testing.

Acids and Bases
Buffers
Routine Chemical Reagents
Silica Gels
Solvents

Anhydrous Grade
Ideal use in organic synthesis, organometallics, oligonucleotide synthesis, combinatorial chemistry and other applications requiring extremely low levels of water. Water content ranges from typically 10 to 30ppm and do not require additional drying in your lab due to our low residue levels.

Solvents

Biotech Grade
The Biotech line of solvents is characterized by not only low water content, but also minimal residue and clean UV spectra. Purified for biotechnology applications such as peptide and oligonucleotide synthesis, protein sequencing and electrophoresis.

Solvents

CHROMASOLV® Grade
Designed for use with HPLC instrumentation and organic synthesis applications. CHROMASOLV HPLC solvents are glass distilled; submicron filtered and undergo rigorous specification testing to provide you with lot-to-lot consistency.

Solvents

CHROMASOLV® Gradient Grade
The same high quality as our CHROMASOLV for HPLC, but with added testing for suitability in HPLC with gradient analysis and spectrophotometry. Eliminates any impurity peaks, which could be caused by the solvent rather than by the compound being tested – Solvent impurity peaks are less than 0.005 absorbent units.

Solvents

CHROMASOLV® Plus Grade
Manufactured to go beyond our CHROMASOLV for HPLC to be your high-purity, multipurpose solvent. Tested for suitability in HPLC with gradient analysis, spectrophotometry, environmental testing and some LC-MS applications.

Solvents

CHROMASOLV® LC-MS
The LC-MS solvents are designed specifically with low content (<100 ppb) of alkaline impurities, such as calcium, magnesium, potassium, and sodium, which can interfere in the analysis by forming artifacts with the analyte. CHROMASOLV LC-MS solvents are also run through specific UV-spectroscopic quality control tests to guarantee the traditional CHROMASOLV specification.

Solvents

Reagent Grade
Purity ≥95%; for general laboratory use.

Acids and Bases
Routine Chemical Reagents
Solvents

ReagentPlus® Grade
Purity ≥98.5% guaranteed analysis. Used where higher purities are required such as specialty organic synthesis, preparative scale liquid chromatography and glassware cleaning.

Acids and Bases
Routine Chemical Reagents
Solvents

Spectrophotometric Grade
High-purity solvents with low UV absorption; used in spectrophotometry (UV, visible and IR).

Acids and Bases
Solvents

USP
Meets or exceeds testing specifications of the USP. Used in food and drug applications and cosmetics.

Routine Chemical Reagents

Technical Grade
Chemicals that do not have an established standard set for quality and impurity levels; for general laboratory use.

Routine Chemical Reagents

TraceSelect
Products developed for sample preparation and analysis in the ppm and ppb level. The blank values for metal traces are typically below 0.01mg/kg (0.01 ppm).

Acids and Bases

TraceSelectUltra
Products designed for the ultra trace analysis level down to ppb and ppt. Typical metal trace impurities are below 0.1µg/kg (<0.1ppb) and in some cases down to the ppq level. Consequently, these products are delivered in PFA bottles.
