Distinction between sodium chlorite and sodium hypochlorite by ion-chromatography

A new method for distinguishing between sodium chlorite and ion chromatography is described. Under the operating condition (gel TSK DEAE-5PW glass column 8.0 mm diameter x 7.5 cm with an aqueous solution containing 20 mM sodium carbonate, 10 mM sodium hydroxide and ethylenediamine 4) And an electrochemical detector (Toso EC-8000, -200 mV, Ag electrode) are clearly separated and detected chlorite and hypochlorite anions and the retention times (tR) are 6.0 and 4.6 min.

Dithiothreitol for sale

Product Name: dithiothreitol
CAS Number: 3483-12-3
Molecular formula: C4H10O2S2
Molecular Weight: 154.253
Product Description: As sulfur DNA preservatives and reducing agents. Thiols DNA tends to the end of the sulfur atoms in the solution to form dimers, especially in the presence of oxygen. This second polymerization greatly reduces the coupling reaction, some experimentation, such as the DNA biosensor in solid efficiency; Suppressing the addition of DTT to a DNA solution, the reaction after a period of time reduces the polymerization of the DNA. DTT is also frequently used in reducing disulfide bonds in proteins that can be used to prevent proteins, which are formed between the intramolecular or intermolecular disulfide bonds Cysteinproteins. However, DTT is often able to restore embedding within the protein (solvent) and disulphide bond structure, the reduction of the disulfide bond is often necessary for the denaturation of primary proteins (heating at high temperature or Joining denaturants such as 6 M guanidine hydrochloride 8 M urea or 1% SDS).
