    Choosing the right elemental analysis: 5 tips

    ICP-OES or specialist instruments for halogens and sulphur? We walk you through how to find the right technology for your measurement needs most quickly.

    There is rarely a perfect technique for all elements; the reality in the laboratory is often a combination. This guide helps you select the right starting point and avoid duplicate investments.

    Labsense supplies sample preparation for ICP-OES (Katanax fusion and Preekem microwave digestion), halogen and sulphur analysers (Nittoseiko), and associated reagents and CRM (AnalytiChem). We recommend based on sample type, concentration levels and operating environment — not based on what happens to be on the shelf.

    Elemental spectrum

    Which elements and concentration levels need to be covered?

    ICP-OES reaches down to ppb level for solutions and covers most metals and metalloids. Halogens and sulphur are measured by combustion + IC/UVF (Nittoseiko AQF/NSX). List the elements and target limits first.

    Sample type

    Solid sample, solution, or direct measurement?

    Solutions suit ICP-OES, where sample preparation governs quality (Katanax fusion digestion for hard-to-dissolve matrices, Preekem microwave for organic and environmental samples). Complex matrices (coal, biota, food) suit dedicated analysers that measure solid samples directly without dissolution.

    Throughput & response time

    Is real-time required or is batch sufficient?

    Dedicated analysers (halogen, sulphur) give minute-level results directly on the sample. ICP-OES requires solution preparation first, where automated sample preparation (Katanax X-series, Preekem WX-8000) determines total cycle time. Consider the value of rapid process feedback.

    Regulations & standards

    Which standard or method must be followed?

    ISO 17025 accreditation, EPA methods, ASTM, and industry-specific standards often dictate the technology. Verify that the chosen method is accreditable for your application area before comparing instrument prices.

    Total cost

    What is the cost of ownership for the instrument over ten years?

    Reagents, CRMs, gas, crucibles, accredited calibration, spare parts, and technician time often constitute a larger portion of the total cost than the instrument itself. Request a TCO calculation, not just a list price.

    Should we map out your method portfolio?

    Submit the elements you measure, on which samples, and against which standard. We will respond with a technical recommendation that meets the need without unnecessary duplicate investments.
