Speciation Analysis


Analytical Standards for Single & Dual Speciation Analysis

Speciation analysis has become common in many testing fields, including in the environmental, food and pharmaceutical testing labs. To analyze species in a sample requires Certified Reference Materials (CRMs) for sample verification and method validation.
SPEX CertiPrep offers a wide variety of speciation standards, certified to the strictest ISO Guide 34 guidelines and tested on our own LC-ICP-MS.
Single and Multi-Element Speciation Standards include Arsenic (+3), Arsenic (+5), Chromium (+3), Chromium (+6), Selenium (+4), and Selenium (+6).
Please see our Guide to Speciation and Speciation Product Flyer for product details.


What is speciation analysis?
The International Union of Pure and Applied Chemistry (IUPAC) defines speciation as ‘the distribution of an element amongst defined chemical species in a system’. Speciation analysis is the analytical process of identifying and/or measuring the amounts of one or more individual chemical species in a sample.

Why Buy American?2
  •  JobsThe most common reason shoppers buy American made products is to help save or create jobs in the United States.
  • Lower Carbon Footprint. Products made overseas have a higher carbon footprint than U.S. made goods. Goods made in China or India have to be shipped all the way across the ocean to reach American stores, burning fossil fuel and spewing out greenhouse gases with every mile they travel.
  • Less Pollution. One reason it’s cheaper to make goods in developing countries is that many of them have few or no regulations to protect the health of the air and water. Many factories overseas that produce goods for export to the United States also produce large amounts of hazardous chemicals that pollute the air, water, and soil.
  • A Stronger Economy. Buying American-made goods doesn’t just support the workers who make those goods. Its benefits also ripple out through the entire economy. When American factories prosper, they hire American construction firms to expand their buildings, American accounting firms to handle their money, and American energy suppliers to provide them with power.
