（China）GC-7890 Ditert-butyl Peroxide Residue Detector
Introduction
Melt-blown cloth has the characteristics of small pore size, high porosity and high filtration efficiency, and is the core material of mask production. This instrument refers to GB/T 30923-2014 plastic Polypropylene (PP) Melt-blown Special Material, suitable for polypropylene as the main raw material, with di-tert-butyl peroxide (DTBP) as the reducing agent, modified polypropylene melt-blown special material.
Methods the principle
The sample is dissolved or swollen in toluene solvent containing a known amount of n-hexane as internal standard. An appropriate amount of solution was absorbed by microsampler and directly injected into gas chromatograph. Under certain conditions, gas chromatographic analysis was carried out. DTBP residue was determined by internal standard method.
