Iyo ine yakanaka buffering kugona muhuwandu hwepH 6.8-8.2, uye inogona kudzora anogara ekemikari Book pH kwenguva yakareba. Kana iyo yekumisikidza iri 10-50mmol / L, iyo yakajairika tsika yepakati ine 20mmol / L 4-hydroxyethyl piperazine ethanesulfonic acid inogona kuve yakanaka buffering uye haina chepfu mumasero.
Kugadzirira nzira:
Kuita kwakamiswa, kusefa, uye munyu wakanatswa wakagezwa ne200 ml ye ethyl acetate (EA). Iyo filtrate yakarukwa yakaomeswa kuwana 2.6 g yeHEPES (4-hydroxyethyl piperazine ethanesulfonic acid) yakasimba.
