Frequently Asked Questions — for UHPLC
for UHPLC indicates that the chemical has been purified and tested specifically for use in ultra-high-performance liquid chromatography. Key specifications typically include controlled UV absorbance at common detection wavelengths, low non-volatile residue, controlled moisture content, and verified lot-to-lot consistency. for UHPLC is used for mobile phases, sample preparation and analytical standards in this workflow.
ACS and AR grades are general-purpose analytical purity tiers. for UHPLC adds workflow-specific specifications — particularly UV absorbance cutoffs and impurity profiles that matter for chromatographic detection. Many for UHPLC solvents also meet ACS or AR specifications, but the reverse is not always true. For routine analytical work outside chromatography, ACS or AR grade is often more economical.
Yes. Premium grades such as UltraPureChrom™, 'for HPLC plus', or grades dedicated to MS work generally exceed the specifications of standard chromatography grades. Use a higher tier when method sensitivity, regulated workflows, or trace analysis demand it. Switching down to a lower-tier grade is not recommended without method revalidation.
Standard chromatography grades can support many LC-MS applications, but for trace MS work or methods sensitive to ionic background and metals, dedicated LC-MS or UHPLC-MS grade solvents are recommended. These include additional metal-content testing and lower particulate levels.
