Cayman Chemical Propoxur-d3 10mg
An internal standard for the quantification of propoxur by GC- or LC-MS
Electron Microscopy Sciences MXS Calibration Standard MXS 702CE for SEM, Pin 700 nm, 700 nm Spacing
EMS offers a series of calibration standards with one and two dimension calibrated patterns. These standards are created utilizing holographic interference of a particular laser frequency. They are typically accurate to <1% across the entire surface of the standard. These reference standards are remarkably durable under typical operating conditions. The surface contamination behavior is also very good. There are no better sub-micron reference standard available in this price range.
Mount: Pin
Spacing: 700 nm
Structure: Arrayof Posts
Material: W-coated Photoresist on Si

SPECTRUM QUALITY STANDARDS Daily Check Standards for D4815 and/or D5599
The EPA requires calibrations be checked using a Calibration Check Standard at least once per analysis batch or once per 10 samples; and an Independent Reference Standard at least once per analysis batch or at least once per 100 samples. Additionally, the Calibration Check Standard and the Reference Standard must be made from different lots of raw materials and by different persons. Spectrum manufactures Check Standards in compliance with EPA regulations. They consist of a Calibration Check Standard, a Reference Standard, and a Reference Blank.
