Iminodiacetic acid chelating resin column

Iminodiacetic acid chelating resin columnThe filler of AnL IC-M column (1.0 cc, 2.5 cc) is NH4+type iminodiacetic acid chelating resin. The column capacities of the two specifications (1.0 cc and 2.5 cc) are 0.4 and 1.0 meq, respectively.

Iminodiacetic acid chelating resin columnThe main function of IC-M column products is to adsorb, concentrate or remove heavy metal ions in complex sample matrices at pH greater than 4. In this case, the treatment column allows alkali metal and alkaline earth metal ions to pass through. Generally speaking, transition metal ions can be leached through with 0.5 mol/L HNO3.

The "GB 5009.12-2023 National Food Safety Standard for the Determination of Lead in Food" released in September 2023, "First Method Graphite Furnace Atomic Absorption Spectroscopy", compared with GB5009.12-2017, added a pre-treatment method for desalinated samples that uses a column of iminodiacetic acid based chelating resin (1mL, 500mg), which can effectively enrich heavy metal ions such as lead and cadmium, remove interfering metal ions (sodium and potassium ions), and meet the requirements for the determination of lead content in high salt samples.
