Sherwood : What instruments for the photométrie of flame and analysis of the chlorure?

A recognised British manufacturer, Sherwood designs analytical instruments for the rapid measurement of alkali ions by flame photometry, as well as solutions for chloride analysis. Its robust, intuitive instruments serve the needs of quality control, R&D and teaching laboratories in the food and beverage, environmental and chemical sectors. With practical design, proven signal stability and a highly competitive cost per test, Sherwood is a trusted partner for standardising routine Na/K/Li/Ca determinations.

UK-born instrumentation expertise

Based in the United Kingdom, Sherwood has grown around a clear core mission: to supply simple, accurate and durable laboratory instruments for ion determination. With decades of experience in flame photometry, the brand has built a coherent portfolio – instruments, accessories, standards and consumables – to deliver reproducible measurements in real-world sample matrices. Its engineering culture prioritises mechanical reliability, signal stability and ease of maintenance, supported by approachable technical support. Today, Sherwood supplies its instruments internationally via a network of specialist partners, and continues to optimise ergonomics, user safety and the traceability of results for modern laboratories.

Expertise and areas of specialisation

Sherwood’s expertise centres on instruments dedicated to the rapid measurement of cations by flame photometry: sodium (Na), potassium (K), lithium (Li) and, depending on configuration, calcium (Ca). This technology, widely adopted for its time/cost/accuracy balance, is the method of choice in laboratories processing large numbers of samples and requiring consistent repeatability. Sherwood instruments stand out for fast start-up, dedicated filters, optimised flame stability and straightforward calibration functions that are easy to secure for routine work. They cover a wide range of applications: salinity and minerals in the food & drink sector (beverages, brines, dairy), control of fertilisers and agricultural inputs, waters and effluents in environmental analysis, as well as R&D/teaching. The brand also provides solutions for the measurement of chloride in aqueous matrices, useful for quality control. Sherwood supplies its systems with accessories (air/gas supplies, diluters, consumables, standards) and clear documentation to integrate the instrument into existing methods, trace calibrations and simplify preventive maintenance (nebuliser, burner, fluid lines). In partnership with Dutscher, laboratories benefit from application advice, meticulous commissioning and responsive after-sales support to safeguard performance over time.
