RA-915 Lab

Product catalog summary
Overview: The RA-915 LAB is a direct thermal decomposition mercury analyzer with Zeeman background correction, designed for analyzing solids, liquids, and biosamples. It offers low detection limits, high selectivity, and a broad analytical range, with minimal maintenance and operating costs.
Key Features:
  • Direct analysis without sample pretreatment or reagents, minimizing waste.
  • Uses air as a carrier gas, eliminating the need for compressed gases.
  • Capable of analyzing a wide range of sample types directly.
  • Fast, cost-effective analysis with a programmable furnace for optimal decomposition.
  • No memory effect, allowing sequential analysis of samples with varying mercury concentrations.
Principle of Operation: The analyzer uses atomic absorption spectrometry with Zeeman correction to measure mercury absorption at 254 nm. Samples are decomposed in a furnace, and gaseous products are analyzed in a heated cell to prevent recombination and contamination.
Applications: Suitable for analyzing mercury in various matrices, including soils, sediments, rocks, crude oil, coal, waste waters, food, biosamples, and more. Complies with standards such as ASTM D6722, US EPA methods, and EN/TS 17286.
Specifications:
  • Measurement range: 0–2,000,000 ppb (µg/kg).
  • Detection limit: 0.2 ppb (µg/kg).
  • Sample boat capacity: 5,000 mg / 2,800 µL.
  • Analysis time: 1–5 minutes.
  • Thermoscanning range: 50–950 °C.
  • Dimensions: 450×840×460 mm; weight: 57 kg.
Software: The RAPID software is user-friendly and complies with FDA 21 CFR part 11. It supports user management, electronic signatures, real-time visualization, and data storage and reporting.
Warranty and Services: The RA-915 LAB comes with a 1-year warranty. Installation and commissioning services are available through Lumex Instruments or certified distributors.

EASY-TO-USE VERSATILE INSTRUMENT FOR YOUR APPLICATIONS Mercury is an extremely toxic, ubiquitous pollutant. There is a broad range of anthropogenic sources of mercury emissions to air and releases to water and soil. Mercury accumulates in deponent media and food chains and causes adverse effects on the environment and human health if consumed or inhaled. The Minamata Convention on Mercury prescribes reducing mercury usage in various products and processes, monitoring and control of mercury emissions to air and releases to land and water. Formidable diversity of samples requires precise, cost...

SENSITIVE AND SELECTIVE ANALYSIS WITHOUT MATRIX EFFECTS Lumex Instruments’ state-of-the-art technology of Atomic absorption spectrometry with Zeeman correction for background absorption makes interference-free measurements easy and quick. Extended analytical range of up to 2 000 000 ppb (pg/kg) covers all possible applications and samples. A radiation source of the analyzer is placed in a strong permanent magnetic field. The mercury resonance line is split into three polarized Zeeman components. A photodetector detects only the radiation of the o-components, one of those falling within the absorption...
