Why Have These Capabilities?

Chemical Solutions Ltd. provides analysis through Inductively Coupled Plasma – Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma – Optical Emission Spectrometry (ICP-OES) for trace metal analysis and more. These techniques generally have less interference and are also faster than both Atomic Absorption (AA) and Graphite Furnace AA (GFAA) when analyzing for multiple elements in a single sample. Detection limits are usually lower than GFAA. Its productivity, accuracy, and precision at low levels, make ICP-MS and ICP-OES the predominant choices for research, regulatory, and quality assurance applications. Because of these features, CSL has the ability to analyze an abundance of matrices for most of the naturally occurring elements.

Current Instrumentation:

  • PerkinElmer ELAN 9000 ICP-MS – used to assay trace and ultra-trace elements at part per billion (ppb) and lower levels
  • PerkinElmer ELAN DRC II – used to assay trace and ultra-trace elements at ppb and lower levels, specifically aiding in arsenic, chromium, iron, and selenium analyses
  • SpectroGenesis FES ICP-OES – used to assay higher concentration (% level) elements
  • PerkinElmer NexION 300D ICP-MS – has 3 operating modes and 2 interference removing techniques: Standard Mode, DRC (Dynamic Reaction Cell) Mode, KED (Kinetic Energy Dispersion). It can analyze samples faster and at lower detection levels.
  • PerkinElmer 8300 ICP-OES – has a high-performance solid state detector and segmented-array charge couple to allow for exceptional resolution and superior detection and line selection
  • PerkinElmer NexION 350X ICP-MS – allows KED or Reaction Mode with multiple sample introduction systems to accommodate a wider variety of sample types and applications
  • Agilent 7700X ICP-MS – may be run in conjunction with the Metrohm IC or separately – used to assay trace and ultra-trace elements at part per billion and lower levels
  • Metrohm IC – Ion Chromatography instrument used primarily for speciation of chromium, mercury and arsenic

Sample Preparation:

  • Environmental Express AutoBlocks – used for performing automated open-vessel acid digestions
  • Environmental Express HotBlock – used for performing manual open-vessel acid digestions
  • Milestone Microwave UltraWAVE – used in putting difficult matrices into solution
  • Milestone Microwave UltraWAVE II – used for complete digestion of extremely difficult samples with no pressure venting, assuring no loss of volatile elements
  • Milestone Microwave Ethos UP – used to accommodate large sample sizes and reagent volumes
  • Milestone Microwave Ethos UP II – a high pressure microwave, this unit is used to accommodate high capacities with a 16 position carousel and a high capacity rotor that increases throughput.
  • Milestone traceCLEAN – an acid steam cleaning system that helps assure that our lab experiences zero downtime
  • Milestone traceCLEAN II– an acid steam cleaning system that helps assure that our lab experiences zero downtime

Heavy Metals Analyses

The most common metal impurity analysis as per most regulations.

Mineral Analyses

Used when verifying label claim specifications.
Excipient analyses for concentration of minerals in raw and finished products for multi-vitamins, mineral blends, and APIs, etc.

Total Quant II Elemental Scan

In the Total Quant II Scan, a semi-quantitative analysis, approximately 65 elements are scanned. A 21 element standard is used to calibrate. The values for the remaining elements are estimated based upon internal response factors. Detection limits may vary depending upon sample matrix and dilution required.

Isotope Dilution

Isotope Dilution is used for highly accurate and precise measurements of elemental concentrations. The method is based upon the addition of a known amount of an enriched isotope of the quantifiable element to a sample, thus altering the naturally occurring isotopic ratio for the element.

This method is preferred over others for several reasons:

  1. It enhances accuracy and precision in a variety of complicated matrices even at very low levels.
  2. Quantitation is accomplished using a direct mathematical calculation independent of problems from an external calibration curve or inadequately matched internal standards.

The isotope dilution method is a very accurate and precise method. It is suitable for determination of trace metals in samples that need low level detection. Since this method has an ideal internal standard that corrects matrix effects, isotope dilution is perfect for samples with complicated matrices.

Sample Preparation

CSL is able to analyze the wide spectrum of matrices above by utilizing the following equipment:

  • Environmental Express AutoBlocks – used for performing automated open-vessel acid digestions
  • Environmental Express HotBlock – used for performing manual open vessel acid digestions
  • Milestone Microwave UltraWAVE – used for putting difficult matrices into solution
  • Milestone Microwave Ethos UP – a high pressure microwave, this unit is used to accommodate high capacities with a 16 position carousel and a high capacity rotor that increases throughput.

Chemical Solutions, Ltd. is recognized by leaders in the industry, not only as an FDA registered and audited analytical testing lab, but by PJLA, NELAP and many others.
