This note describes a method to rapidly set up the 210-MS GC/MS system for the analysis of 64 semi-volatile compounds using EPA 8270D.

This document describes the method of using the Varian 225-MS ion trap mass spectrometer and V:Results™ GC/MS software to determine phthalate compounds in plastic toys. These compounds are health hazards in polyvinyl chloride (PVC) toys and have raised significant concerns among safety regulators.

This document discusses the automation technology in infrared analysis, particularly the application of auto samplers. It also mentions the possibility of automating microscopic analysis using an infrared microscope. These automation technologies are essential for laboratories that need to analyze a large number of samples. The document also mentions Varian's Ex model infrared spectrometer.

Varian's FT-IR spectrometers are known for their high infrared energy in the sample compartment, resulting in higher signal-to-noise ratios and sensitivity. This article compares the real-world performance advantage of Varian's Scimitar series over another manufacturer's product.

This application note describes the use of digital signal processing (DSP) technology to demodulate detector signals in Fourier transform infrared (FT-IR) instruments for polarization modulation IR measurements.

This document describes how to focus a sample on the UMA 600

This article introduces the important sealing and desiccation factors in the design of a FT-IR spectrometer.

This manual introduces how to use Varian DMS 90 spectrophotometer to determine protein concentration.

Describes some applications of UV-Visible derivative spectroscopy, including clinical, pharmaceutical, biochemical (life sciences), inorganic and other areas. It introduces the basic principles and application methods of derivative technology.

The document introduces the features of Varian's Turbo-V K-G series high performance turbo system, which has the highest pumping speed, maintenance-free and no oil refill

This document is an application note on Varian's 500-MS LC ion trap mass spectrometer. It discusses the use of Varian's Mass ID software for the deconvolution of biomolecules.

This application note describes a multi-residue method for polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs). The method was used to analyze 16 PAHs, 17 PCBs and 24 OCPs at different concentration levels in a single run. The results showed that the method is suitable for the analysis of these compounds.

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.

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.
