Frequently Asked Questions — Hydrophilicity
What does Hydrophilicity mean?
Hydrophilicity is a defined analytical purity tier suitable for workflows requiring a specific validated property. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Hydrophilicity is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.
When should I choose Hydrophilicity over a higher tier?
Choose Hydrophilicity for routine analytical work where the method tolerates the stated impurity limits. Move up to HPLC grade, UltraPureChrom™, or a pharmacopoeia grade (USP, BP, JP, ChP, Ph.Eur.) when your method demands tighter UV absorbance, trace metal limits, or regulated compendial documentation.
Is Hydrophilicity suitable for use as an HPLC mobile phase?
Not by default. Standard analytical purity tiers do not always meet UV absorbance and fluorescence specifications needed for HPLC. For chromatography, choose HPLC grade, HPLC Gradient Grade, or for HPLC plus. For LC-MS work, choose for LC-MS or for UHPLC-MS.
Does Hydrophilicity include a Certificate of Analysis?
Yes. Every lot of an analytical-grade reagent ships with a Certificate of Analysis listing tested specifications. SDS and additional documentation are available on the product page or by request.
What pack sizes are available?
Solid reagents are typically offered in 25 g, 100 g, 500 g and 1 kg units; liquids in 500 mL, 1 L, 2.5 L and 4 L. Bulk and custom packaging are available through the Bulk & Custom Quote workflow.
