SPECTRO Analytical Instruments has announced the newest version of its SPECTROMAXx Arc/Spark OES analyser. The ninth generation SPECTROMAXx LMX09 analyser provides reduced cost of ownership with lower consumables, plus advanced diagnostics and easy maintenance that increases availability and prevents downtime. Features include: Fast, simple standardisation with SPECTRO’s proprietary iCAL 2.0 calibration logic — needing only five minutes and a single sample per day. Plus, iCAL 2.0 automatically compensates for most changes in environmental temperature or pressure. Significant reductions in argon (Ar) gas consumption—6–12 % during operation and 18–64 % during standby—without impacting performance. An expanded wavelength range with the option of a new UV optic to handle a spectral range from 120 nm to 235 nm, extending analyses to elements such as nitrogen (N), carbon (C), sulfur (S), and phosphorus (P) as well as hydrogen (H) and oxygen (O) in titanium (Ti) base materials. Improved ease of use with routine, trouble-free analysis of 10 matrices, 68 methods and 56 elements, plus easier access and new software features. SPECTRO’s SPARK ANALYZER Pro software, which has application profiles, automatic program selection and argon saver. New functions include the ability to recall stored spectra for later reevaluation/recalculation; extended data export functions; quick check programs for the rapid analysis of iron and aluminium; and onsite upgrades/additions of analytical methods without any hardware changes. Hardware improvements include a new spark stand configuration with easier access for automation options; a new optic isolation concept for greater temperature stability; UV optic (on SPECTROMAXx Advanced); an ultra-robust, high-power plasma generator with spark frequencies up to 1000 Hz; start/stop averaging button/spark indicator; and on/off safety switch to control line/mains power. Adapter kits offering a variety of flexible, easy-to-use solutions to meet the wide range of analysis requirements of material control—from adjusting for differing sample shapes and sizes to optimizing positioning on the spark stand.

The new analyser is available in two models, differing only in their optical systems. The basic SPECTROMAXx features SPECTRO’s proven single air optic with high-resolution CCD sensors. Its solid design resists fluctuations due to ambient temperature changes. It handles elemental wavelengths from 233 nm to 670 nm. The new SPECTROMAXx Advanced adds the new UV optic with four high-resolution CMOS detectors, extending the wavelength range to 120–235 nm. A closed system circulates gas through SPECTRO’s UV Plus cleaning cartridge, eliminating extra argon consumption and contamination risks. Both versions feature a temperature-stabilised system that heats both optics. Both are available as floor-mounted units with optional PC stands or benchtop models for a minimum footprint.
