    Application: Ultra low background additive for LC-MS analysis of poly- and per-fluoroalkyl substances, suitable for EPA Methods 533 and 537.1
    Concentrated Formic Acid slowly decomposes to carbon monoxide and water and the pressure built up can cause an explosion of the sealed glass bottle.
    As a safety measure we fit larger glass bottles with a closure featuring a venting valve. Bottles with a non-vented closure should have pressure released regularly.
