Capillary electrophoresis with contactless conductometric detection for rapid screening of formate in blood serum after methanol intoxication

Popis výsledku v původním jazyce

A new method for rapid, direct determination of formate in blood serum samples by capillary electrophoresis with contactless conductometric detection is presented. A selective separation of formate was achieved in approximately 1 min using an electrolytesystem comprising 10 mM L-histidine, 15 mM glutamic acid and 30 mu M cetyltrimethylammonium bromide at pH 4.56. The only sample preparation was dilution (1:100) with deionized water. The limit of detection and limit of quantitation was 2.2 mu M and 7.3mu M, respectively, which corresponds to 0.22 mM and 0.73 mM in undiluted blood serum. The method provides a simple and rapid diagnostic test in suspected methanol intoxication cases. The method has been successfully tested on determination of formate inblood of a patient admitted to the hospital under acute methanol intoxication. The peak concentration of formate detected in the patient blood serum was 12.4 mM, which is 10- to 100-fold higher than the normal values in healthy populatio
