Abstract
A reagent for use in the measurement of hemoglobins by liquid chromatography, the reagent comprising a nonionic surfactant selected from the group consisting of: (i) polyoxyethylene (10) decyl ether; (ii) polyoxyethylene (6) 2-ethylhexyl ether; (iii) polyoxyethylene (9) isodecyl ether; (iv) polyoxyethylene (10) nonyl ether; (v) polyoxyethylene (16) isostearyl ether; (vi) polyoxyethylene (20) behenyl ether; and (vii) polyoxyethylene (20) polyoxypropylene (6) decyltetradecyl ether.
Claims8
A method of measuring one or more hemoglobins by liquid chromatography, comprising:
- treating a hemoglobin-containing sample with a reagent comprising a nonionic surfactant,
- performing liquid chromatography using the hemoglobin-containing sample treated with the reagent, and
- detecting and measuring at least one peak of the one or more hemoglobins in a liquid chromatogram to quantify the one or more hemoglobins,
- wherein said nonionic surfactant is one or more nonionic surfactants selected from the group consisting of:
- (i) polyoxyethylene (10) decyl ether;
- (ii) polyoxyethylene (6) 2-ethylhexyl ether;
- (iii) polyoxyethylene (9) isodecyl ether;
- (iv) polyoxyethylene (10) nonyl ether;
- (v) polyoxyethylene (20) behenyl ether;
- and
- (vi) polyoxyethylene (20) polyoxypropylene (6) decyltetradecyl ether.
