High Speed GPC Analysis by Nexer GPC System: Calculation of Molecular Weight and Quantitative Analysis of Additives

Measurement of the molecular weight distribution of polymers is one field of HPLC utilizing the size exclusion mode and has been called GPC (gel permeation chromatography) for a long time. Recent requirements for increased throughput by high speed analysis are also considered as a priority in GPC, which is an established analytical technique. In ...

Quality standards for children

Mr. Benjamin, Managing Director of Distribution N KID Group said that at present, the Vietnamese children's toy market has 70% non-branded, only 30% is branded and safe. As noted, Vietnam currently has about 20.8 million children aged 0-12. This is a potential consumer segment that businesses have not fully exploited. Thus, to see that ...

Analysis of Residual Solvents in Pharmaceuticals by Water-Insoluble Samples Using N2 Carrier (JP17 Supplement II, USP 467)

Residual solvents in pharmaceuticals are classified from Class 1 to 3 based on their potential human health risk. Since these compounds are strictly controlled, highly sensitive analysis is required. Helium (He) is generally used as the carrier gas, but analysis using an alternative carrier gas such as N2 has also been in demand recently as He ...
