AgroMAT™ CP-1, Compost

AgroMAT™ Matrix Reference Materials for agricultural laboratories are a cost effective solution for validation of internal standards or routine quality control verification of various analytical techniques for multiple parameter testing and can be an invaluable component of any laboratory quality control program.

AgroMAT™ CP-1 is a compost Matrix Reference Materials for the analysis of metals, pH, organic matter, nitrate and nitrogen.

  • Consensus certification removes any chance of analytical bias
  • Each Matrix Reference Material is certified through a round-robin study employing specific methods of analysis - independent verification from multiple laboratories
  • Sampling, handling and extraction method information is included
  • Includes Certificate of Analysis listing Consensus Values, Confidence and Tolerance Intervals, and Instructions for Use - complete documentation for audit purposes

The Matrix Reference Material CP-1 is a compost (not spiked or fortified) with a particle size of -35 mesh. It is designed to be used for quality control verification, internal standards validation or methods development for compost analysis by different techniques for the listed parameters. Not intended for calibration.

Expiry: 2 years from date of shipment

AgroMAT™ Matrix Reference Materials are available for clay soil, sandy soil and compost.

Unit Size: 100g

Consensus values were the result of an inter-laboratory study involving fourty-seven international laboratories. Each laboratory was asked to supply analysis data for a specific list of elements. Not all the laboratories supplied data for the different parameters.

Most of the participating labs employed an extraction method based on EPA-3050B (or NF EN ISO 11466). HNO3, HNO3/HCl or HNO3/HCl/H2O2 digestion method was used. ICP-MS and ICP-AES have been used for metals quantification by most of inter-laboratory Study participating laboratories. The % humidity has been determined by drying at 105°C. Organic matter was determined by ignition at 360°C and 550°C. Most laboratory used colorimetry, Ion Chromatography (IC) or Segmented Flow Analyzer (SFA) to measure nitrates. Water extraction method and pH-meter was used for soil pH. Most participating labs used soil ratio 1:1 or 1:2 (soil:water) for pH testing. Combustion or Colorimetry has been used for % nitrogen
