Atomic Absorption

  As part of a comprehensive line of AA supplies, SCP SCIENCE offers high performance Hollow Cathode Lamps in both the 1.5’’ and 2.0’’ diameter formats. High density, pyrolytically coated, Graphite Furnace Tubes, a complete range of Matrix Modifiers, AA Reference standards, and our hollow Cathode Lamps, are extensively stocked for prompt service. Inquire about our popular special offer of a free AA Standard with the purchase of each package of Graphite Tubes or hollow cathode lamp.

AA Single Element Standards

Popular standards are available for Flame and Graphite Furnace Atomic Absorption. Each standard includes a detailed Certificate of Analysis and direct traceability to NIST.

Autosampler Tubes

CREA provides a full range of cups or tubes for your autosampler. Our sample cups and tubes are molded either from premium grade polystyrene for clarity, or polypropylene for impact strength and stability to common acids, alkalies, and solvents.

Graphite Tubes

CREA provides a full range of supplies for all your graphite furnace needs. Graphite furnace tubes are made from high-purity, high-density graphite which in turn produces an extremely low coefficient of expansion. Cross-references available for OEM products.

High Purity Acids and Reagents

PlasmaPURE Trace Metal Grade Acids are manufactured with trace metal impurities of less than 1ppb and are intended for ICP, ICPMS, GFAA and flame AA applications above 1ppb.

PlasmaPURE Plus Optima Grade acids are manufactured with trace metal impurities less than 10ppt and packaged in pre-leached Teflon bottles for ultra low level analysis by ICP or ICPMS below 1ppb.

Hollow Cathode Lamps

CREA has a wide selection of non-coded hollow cathode lamps as direct replacements for AAS instruments. Available in the two standard sizes: 2.0” diameter for direct replacement in PerkinElmer®instruments and 1.5” diameter for Varian®, Buck®, Shimadzu®, and other OEMs.

Matrix Modifiers

Matrix Modifiers allow the optimization of analytical conditions to provide better GFAA instrument response and better detection limits. All commonly used products are available in addition to custom formulations.

Quartz Cells

Looking for the best performance available for your instrument? Matrix Modifiers allow for the optimization of analytical conditions to provide better GFAA instrument response and better detection limits. Ionization buffers will increase the free-electron concentration, helping to stabilize the amount of ionization in your sample. Releasing agents bind up potential interference ions, allowing the analyte ion to be available for analysis. All commonly used products are available in addition to custom formulations.
