April 2022—Verichem Laboratories offers two multilevel, protein-based test kits of clinical reference materials for the calibration or calibration verification of lithium assays. Intended for use with direct and indirect ion-selective electrodes, colorimetric assays, and flame photometers, the Electrolyte Standard Kit and Serum ISE Standard Kit contain NIST-verified gravimetric concentrations for lithium. The liquid-stable, ready-to-use materials can also be used for quality control monitoring, method evaluations, post-maintenance testing, and routine troubleshooting.
The Electrolyte Standard Kit features a lithium concentration range from 0.50 mmol/L to 5.5 mmol/L and has a shelf life of 21 months, and the Serum ISE Standard Kit offers a concentration range from 0.20 mmol/L to 4.6 mmol/L with an 18-month shelf life.
