ninhydrin-positive contaminants

English to Lithuanian Science Science (general) Amino Acid Analysis
Pvz.:

A new method for isolation of polyamines from tissues was developed and compared with the butanol extraction method which has been widely used for quantitative determination of polyamines. In the new method protein-free tissue extracts are applied to a small Dowex-50 column. The column is washed with appropriate buffers to remove ninhydrin-positive contaminants and the polyamines are eluted.

su ninhidrinu reaguojantys teršalai

Iš Eur-lex:
Amino acid analyser or HPLC equipment with ion exchange column, device for ninhydrin, post column derivatisation and photometric detector.

The column is filled with sulfonated polystyrene resins capable of separating the amino acids from each other and from other ninhydrin-positive materials. The flow in the buffer and ninhydrin lines is provided by pumps having a flow stability of ±0,5 % in the period covering both the standard calibration run and the analysis of the sample.

LT:

Aminorūgščių analizatorius arba HPLC įranga su jonų mainų kolonėle, reakcijos su ninhidrinu įtaisu, darinių gavimo įtaisu ir fotometriniu detektoriumi.Kolonėlės įkrova – sulfoninto polistireno dervos, galinčios atskirti aminorūgštis vieną nuo kitos ir nuo kitų su ninhidrinu reaguojančių medžiagų. Srautas buferinio tirpalo ir ninhidrino sistemose reguliuojamas siurbliais, srauto stabilumas – ±0,5 % kalibravimo tirpalo ir ėminio analizės metu.
