Analytical Chemistry

Successful LC separations depend on mobile-phase solvents with ultra-low UV absorbance, minimal non-volatile residue, and tightly controlled water content. Our HPLC-grade and LC-MS-grade solvents carry gradient-grade specifications and are individually batch-tested against UV cut-off limits at 200 nm, 210 nm, and 254 nm to meet the demands of modern reversed-phase, HILIC, and ion-pair methods.

GC applications require solvents and reagents with extremely low non-volatile residue (NVR) and negligible organic impurity levels to avoid ghost peaks and baseline interference. Our GC-grade solvents and derivatisation reagents are manufactured to meet or exceed the most demanding capillary GC specifications, including pesticide-residue and environmental trace analysis.

Trace and ultra-trace metal analysis by ICP-MS requires acids and diluents with sub-ppb metallic impurity profiles. Our trace-metal-grade nitric acid, hydrochloric acid, and hydrogen peroxide, alongside certified single- and multi-element ICP standards, provide the reagent blank performance and traceability needed for environmental, food, and clinical matrices.

Classical titrimetry — acid-base, redox, complexometric, and Karl Fischer — requires precisely standardised volumetric solutions and high-purity primary standards. We supply ready-to-use titration reagents with guaranteed factor (f) values and primary standards suitable for direct preparation or standardisation of secondary solutions.
