Made-to-order standards formulated to your target elements, concentration, and matrix.
Selecting the right standard comes down to a few key variables.
Match the standard's concentration to your instrument's calibration range.
Choose a single-element standard or a multi-element mix.
Select a matrix that matches your sample type and method.
Confirm the standard's traceability basis meets your accreditation requirements.
Charslton also offers custom and made-to-order standards. Send us your target elements, concentrations, and matrix, and our specialists will confirm a suitable formulation and lead time, typically within 1 working day.
Every standard ships with a certificate of analysis stating certified values, traceability, and expiry or retest dating.
Every standard is supplied with documentation stating its certified values, traceability, and expiry or retest dating.
Our standards are NIST traceable, supporting laboratories that require full certificates of analysis in Singapore.
This documentation applies across our AAS, ICP, ICP-MS, and ion chromatography ranges.
Our standards are NIST traceable, so laboratories requiring full certificates of analysis in Singapore can rely on Charslton for both the standard and its documentation.

Need help choosing an inorganic reference standard? Describe your instrument, target elements, and method to our specialists, and we will recommend a suitable standard.
Our support covers product selection, method, and application questions, along with post-purchase troubleshooting, so you have one point of contact throughout your project.
For laboratories setting up a new method or switching suppliers, this removes the guesswork of comparing specifications alone. Most enquiries receive a specialist response within 4 hours.
A wet chemistry standard supports classical analytical methods, such as titration and colourimetric analysis. Laboratories use these standards to verify results before reporting.
AAS standards are formulated for flame or graphite furnace atomic absorption instruments, which typically measure one element at a time. Meanwhile, ICP standards support multi-element analysis on ICP-OES and ICP-MS instruments.
Speciation standards distinguish between different chemical forms of the same element, such as different oxidation states. Laboratories use them where toxicity or behaviour depends on the specific form present.
Organometallic oil standards calibrate instruments measuring metal content in oils and petroleum products. They support quality control and contamination testing across the oil and gas industry.
A certificate of analysis states a standard's certified values, uncertainty, and traceability. It confirms the standard is accurate and suitable for calibration or quality control use.
Yes, Charslton Technologies supplies standards formulated to United States and European Pharmacopoeia requirements. These support pharmaceutical method validation and regulatory compliance testing.
Yes, we supply Waters QC standards for verifying water testing method accuracy. These support environmental and public health laboratories running routine water analysis.
Store inorganic standards according to the conditions stated on their certificate of analysis, typically in a cool location away from direct sunlight. Correct storage helps preserve certified values until the expiry or retest date.
Send us your requirements and a Charslton specialist will follow up with product recommendations or a formal quotation within 4 business hours.
