InGuard Na Cartridge

The InGuard Na cartridge is used for the removal of high levels of alkaline earths and transition metals from sample matrices without acidifying the sample. This attribute ensures good recovery of acid-labile analytes such as nitrite. This resin is designed to have very high selectivity for multivalent cations such as calcium, magnesium, and transition metals. The InGuard Na cartridge contains styrene-based, sulfonic acid in the sodium form.
