Evaluation of Effectiveness ofDedicated High Durability Column for UsewithPy-Screener™Ver.2

User Benefits

- Integrated Guard extends column life and reduces the maintenance burden and running costs. - Integrated Guard eliminates the worries of leakage, and adsorption and decomposition of components at the connection site. - Even if peak tailing occurs, the peak shape can be improved by partially cutting off the guard column.

Introduction

The RoHS Directive in the EU designates phthalate esters and brominated flame retardants (polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs)) as regulated compounds and restricts their use in components of electrical and electronic products. Py-Screener Ver. 2 is a simultaneous screening system for phthalate esters, PBBs, and PBDEs which enables simple inspection merely by cutting a small piece of the test sample with a cutter and placing it in a sample cup. Since the release of the former product, Py-Screener Ver. 1, the Py- Screener series has been used by many customers, such as manufacturers of electrical and electronic equipment. On the other hand, some customers who conduct tests frequently expressed a desire for longer life of the analysis column because use of a column in which peak tailing occurs due to column deterioration may possibly affect the quantitation accuracy and repeatability of inspections. To solve this problem, Py-Screener Ver. 2 supports inspections with a newly-developed high durability column (SH-1MS with guard column, P/N: 227-36346-01, Shimadzu Corporation). The column has excellent resistance to deterioration and reduces the maintenance burden and running costs. This article introduces the durability of the column and the effect of maintenance when peak tailing occurs.
