SEASTAR™’s BASELINE® Perchloric Acid is in the class of analytical reagent products commonly referred to as ultra pure perchloric acid, ultra trace perchloric acid, or high purity perchloric acid. Check your requirements to see how these products meet your suitability for your solution techniques ICP, ICP-MS, ICP-OES / ICP-AES, GFAAS, HR-ICP-MS, VPD HR-ICP-MS, etc.

Whether your requirements are for solution or matrix stability, or for a more complex, multiple acid geological digestion technique. SEASTAR™’s high purity products ensure there is no accumulation of the analytes being measured. Check our specifications to verify your analytical requirements. For these analytical techniques, SEASTAR™’s BASELINE® products should meet your most critical requirements.
