Frequently Asked Questions — PureSpectra™
What does PureSpectra™ mean?
PureSpectra™ indicates that the chemical has been purified and tested specifically for use in general spectroscopic analysis. Key specifications typically include controlled UV absorbance at common detection wavelengths, low non-volatile residue, controlled moisture content, and verified lot-to-lot consistency. PureSpectra™ is used for mobile phases, sample preparation and analytical standards in this workflow.
How does PureSpectra™ compare to standard ACS or AR grade?
ACS and AR grades are general-purpose analytical purity tiers. PureSpectra™ adds workflow-specific specifications — particularly UV absorbance cutoffs and impurity profiles that matter for chromatographic detection. Many PureSpectra™ 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.
Can I substitute PureSpectra™ with a higher-tier grade?
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.
Is PureSpectra™ suitable for LC-MS work?
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.
What pack sizes are typically available for PureSpectra™ products?
Liquid products are commonly offered in 500 mL, 1 L, 2.5 L and 4 L glass bottles; solid reagents in 25 g, 100 g and 500 g units. Larger drums and custom packaging (amber, septum-sealed, pre-cleaned) are available on request through the Bulk & Custom Quote workflow.
