LA-ICP-MS – Laser ablation ICP-MS technology

Description

Separates and Quantitates Three Types of Mercury Compounds The method specifies isocratic conditions using a Shim-pack Scepter™ C18-120 metal-free column and a methanol and 0.01 mol/L ammonium as the mobile phase. It can separate three types of mercury compounds: divalent mercury, methylmercury, and ethylmercury. Separates and Quantitates Six Types of Arsenic Compounds This method is for gradient elution using an anion exchange column, 0.025 mol/L ammonium dihydrogen phosphate solution as mobile phase A, and water as mobile phase B. It can separate arsenocholine (AsC), arsenobetaine (AsB), arsenic trioxide (As3+), dimethylarsinic acid (DMA), monomethylarsonic acid (MMA), and arsenic (As5+) forms of arsenic. Separates and Quantitates Six Types of Arsenic Compounds This method uses formic acid as the mobile phase. It can separate six types of arsenic compounds: arsenic (As5+), arsenic trioxide (As3+), monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), arsenobetaine (AsB), and arsenocholine (AsC).
