Analysis of recombinant protein purity and heterogeneity by capillary electrophoresis

Determination of inorganic cations in water samples

INTRODUCTION

The method allows determination of ammonium, lithium, sodium, potassium, magnesium, calcium, strontium and barium cations in samples of natural, potable, and waste water by the capillary electrophoresis method.

MEASUREMENT METHOD

The capillary electrophoresis method for evaluation of cations concentration is based on differential migration and separation of cations in electric field due to the difference in their electrophoretic mobility. Identification and quantitative determination of the analyzed cations is performed by indirect detection measuring UV absorption at 254 or 267 nm wavelength.
