Matrix-Assisted Ionisation in Vacuum (MAIV) is a new ionisation technique which ionises non-volatile compounds producing electrospray ionisation-like spectra. Its simple. matrix-assisted laser desorption/ionisation-like sample preparation allows for rapid analysis. with no requirement for external energy in the form of a laser or high voltage to produce ions. https://mabelandfoxs.shop/product-category/wet-wipes-cover/
