Ultisil Lead oxide (PbO2) Series

Welch Ultisil Lead oxide column was specially designed for the detection of malachite green and colorless malachite green in aquatic products by HPLC methods in SC/3021-2004 standard. Because the colorless malachite green fails to absorb in the visible, it is necessary to use this column to oxidize colorless malachite green to malachite green, which solves the difficulty of UV detection of colorless malachite green.
