Precision & Reliability - Delivering High Standards in Analytical Services

Sheffield Analytical Services (SAS) delivers precise, reliable analytical testing across a wide range of industry sectors - including jewellery, medical devices, automotive, aerospace, and cosmetics. Whether you require routine analysis or bespoke testing, we provide accurate assay reports with flexible turnaround times, including same-day results. Read on to find out more about the very high standards we set and work to here in SAS at Sheffield Assay Office.

Uncompromising Accuracy

Measurement accuracy underpins everything we do. Our testing processes are rigorously aligned with ISO/IEC 17025 standards, and our accreditation is independently assessed each year to ensure consistent quality.

Expert Sample Preparation

Our analysts use precision balances with 0.001 mg readability to weigh test samples. These are then dissolved using proven extraction techniques refined over decades of experience.

Reliable Calibration

Every method we use is calibrated with Certified Reference Materials traceable to NIST. From high-purity gold wires to 316 stainless steel drillings and rare earth metal solutions, these standards are essential to ensuring trustworthy results.

State-of-the-Art Equipment

We continually invest in cutting-edge technology, such as ICP-MS, capable of detecting elements at ultra-low concentrations—as little as 0.5 mg/kg together with ICP-OES to provide high elemental concentrations.

Independent Verification

To further guarantee accuracy, we regularly participate in Proficiency Testing and inter-laboratory comparison schemes. Our outstanding performance in these programs adds another layer of confidence for our clients.

Tailored Testing Solutions

We thrive where high-volume laboratories often fall short - providing flexible, bespoke testing developed rapidly to meet unique customer needs. Our focus on innovation and personal service ensures you get the answers you need, when you need them.
