Answer Posted / kishanpal singh fare labs gurg
Primary standard :
the Primary standards are the NIST ,ISO ASC Standard
tracible materials
.This primary stadards
the solutions which are use for
the calibration of analytical instruments.
also used to standardization of std( Normal & Molar solution
Secondary standards:
are use to routine analysis known as
secondary standards for but Secondary standards are liquid
calibration of analytical instruments.
also used to standardization of std( Normal & Molar solution
