This document describes a new method developed by the U.S. Environmental Protection Agency (EPA) for the measurement of volatile organic compounds (VOCs) in drinking water. The method, known as EPA 524.3, is a direct update of the earlier version of EPA Method 524.2. Key differences include the use of solid acid preservatives, a revised target list, an option for use of selected ion monitoring (SIM), and more flexible guidance for optimizing purge-and-trap parameters. Varian, Inc.'s application lab has chosen to participate in a Secondary Laboratory Demonstration study conducted by EPA to help evaluate the new method. Participants are required to perform acceptable calibration analysis, provide precision and accuracy data, and establish Lowest Concentration Minimum Reporting Levels (LCMRLs) for select regulated compounds.

The X28C010 is a 128K x 8 E2PROM fabricated with Xicor's proprietary, high performance, floating gate CMOS technology. It only requires 5V power and supports a 256-byte page write operation, with a write cycle of only 19µs/byte, allowing the entire memory to be written in less than 2.5 seconds.

This application note describes the tandem mass spectrometry analysis of polybrominated flame retardants for RoHS using the Varian 240-MS ion trap gas chromatograph/mass spectrometer. It provides an overview of polybrominated diphenyl ethers, including their molecular structure and their use in fire retardants for furniture and vehicles. The document also discusses the Restriction of Hazardous Substances (RoHS) directive, which restricts the use of certain hazardous materials in products. It specifically mentions the banned compounds and includes an analysis of DecaPBDE, which is currently exempt from the directive.

The PC817 series is a high-density mounted type photocoupler introduced by SHARP. It has the advantages of high current transfer ratio, high isolation voltage between input and output, and compact dual in-line package. It is mainly used in computer terminals, system appliances, measuring instruments, cash registers, copiers, automatic vending machines, electric household appliances, etc.
