What P S Analytical does

P S Analytical is a privately-held UK instrumentation manufacturer founded in 1983, headquartered in Orpington, Kent, with wholly-owned subsidiaries in Deerfield Beach, Florida and Margate, Queensland. The company designs, manufactures and supports atomic fluorescence spectrometry (AFS) instruments for the ultra-trace determination of six elements — mercury (Hg), arsenic (As), selenium (Se), antimony (Sb), bismuth (Bi) and tellurium (Te) — across laboratory and online/continuous monitoring formats.

The product portfolio spans three core laboratory analyser families (Millennium Merlin, Millennium Excalibur, Sir Galahad) supported by an extensive ecosystem of modules and accessories covering speciation interfaces (GC-AFS, HPLC, thermal desorption), sample preparation (autosamplers, preconcentrators, solid samplers, mercury vapour generators), hazardous-area sampling systems (ATEX/IECEx certified for zone 1/2), and continuous emissions monitoring (CEMS) hardware. The underlying technology couples atomic fluorescence spectroscopy with cold vapour generation (for mercury) or hydride generation (for the other five elements), supplemented by a proprietary Amasil gold trap preconcentration stage that pushes detection limits into the sub-ppt range. Software control is handled in-house via the C210S007 platform and SGv3, with industrial output to MODBUS, TCP/IP, RS232/485, contact closures and 4–20 mA.

Revenue is generated primarily through capital hardware sales of laboratory and online analyser systems, with a recurring tail from proprietary spares and consumables (notably Amasil gold traps and calibration kits) and a smaller professional services stream covering customer-tailored training courses and specialised consultancy (mercury mass balance studies, field measurements, independent measurement services across mercury removal units). Go-to-market is direct enterprise field sales targeting government and private contract laboratories, petrochemical companies (oil & gas exploration, refining, LNG), clinical services, food/feed/beverage producers, mining operators and academic research institutions, supported by the website, LinkedIn, downloadable application notes and capability statements, and participation in industry conferences including LNGCON and ICMGP. No public pricing is disclosed; all quotes are handled via direct contact. The company is privately held with no identified outside institutional investors and remains founder-led.
