In the following, a HPLC/UV method was developed for nine phthalates, see Table 1. A phenyl-hexyl column and a C18 column were used for optimum separation. In addition, binary and ternary gradients using acetonitrile and methanol as organic phases were applied. The performance of the method was evaluated and a real-life sample was measured.

The HPLC-ICP-MS hyphenated technique used allowed to obtain better selectivity and sensitivity. The hexavalent form of chromium was not detected in toys which were tested, which can be attributed to low elution strength of dilute HCl used in the procedure described in the standard and retaining this form of chromium in the toy material.

2013年6月1日 · In this study, six priority phthalate esters in children's toys were measured using a Waters Xevo TQ. MRM mode acquisition technique was utilized for quantitative analysis. This developed UPLCMS/MS method has high sensitivity for the extract samples from most PVC toys in which phthalate esters were added.

In this paper, the use of Ion Chromatography (IC) is shown to be a powerful alternative to HPLC, allowing the analysis of both Cr species in the low ng L-1 range. Although IC chromatographic separation of the two species is simple, sample preparation plays an important role.

An Agilent 1260 Infinity Bio-inert HPLC was used to meet the very low Cr detection limit requirement: G5611A Bio-inert Quaternary pump and G5667A Bio-inert High-Performance Auto sampler.

This application note demonstrates that the Agilent 5977E GC/MSD System pro - vides good performance and a cost-efficient solution to help test the six regulated phthalates in children’s toys. All six phthalates have been clearly spiked and the results show good repeatability and relative standard deviations (RSD%). 2. Introduction.

2002年1月1日 · A HPLC and HPTLC method for the determination of seven phthalates in childcare articles and toys made of PVC is presented. Extraction is performed by dissolving the PVC in tetrahydrofuran.

2019年8月8日 · A high-performance chromatography-photodiode array detection (HPLC-PAD) method has been developed and validated for the identification and quantification of ten phthalates; diethyl phthalate (DEP), diallyl phthalate (DAP), benzyl butyl phthalate (BBP), di-n-butyl phthalate (DBP), dihexyl phthalate (DHP), dicyclohexyl phthalate (DCHP), di-2 ...
