Animal feed analyzer RA-915 Lab

soiloilwater

Overview
RA-915 Lab is an automated laboratory direct mercury analyzer with optional 45-position autosampler. It performs direct thermal decomposition without chemical pretreatment or reagents, producing minimal waste. Designed for environmental, industrial, geological and life-science matrices, the system delivers reliable, high-selectivity Hg analysis and supports a wide dynamic range.

Principle of operation
Direct thermal decomposition followed by atomic absorption spectrometry at 254 nm with Zeeman background correction for interference-free, selective measurements.

Features and benefits

• Direct and rapid analysis of solids, liquids and biosamples
• Low detection limits and high selectivity due to Zeeman background correction
• Extended dynamic range up to 2,000,000 ppb suitable for diverse applications
• No sample pretreatment or reagents required, lowering operating costs
• Safe and simple operation: no compressed gases required (air as carrier)
• No pre-concentration on gold traps, increasing throughput and reducing complexity
• No memory effect: low-concentration samples can follow high-concentration ones immediately
• Programmable furnace for optimized decomposition and mercury thermospeciation studies
• Optional 45-position autosampler with loading-on-the-go capability

Applications
Suitable for direct determination of mercury in multiple matrices, including:

• Soils, sediments, rocks, ores, minerals
• Food, food additives, animal feed
• Crude oil, oil products, naphtha, petrochemicals
• Biosamples: tissues, hair, urine, blood
• Wastewaters, wastes, sludge
• Coal, coke, fly ash, gypsum
• Sorbent traps for stack gases and passive air samplers
• Drugs, cosmetics, plastics, fertilizers and other materials

Standards compliance
Mercury determination with RA-915 Lab complies with widely adopted standards based on direct thermal decomposition, including ASTM D6722, ASTM D7622, US EPA 7473/30B/PS12B, EN/TS 17286, SN/T 4429.2-2016, HJ 923-2017 and others.

Software
RAPID software controls RA-915 Lab and is FDA 21 CFR Part 11 compliant. It provides:

• Data acquisition, processing and reporting
• Real-time visualization of selective and non-selective absorbance
• Databases for calibrations and measurement storage
• Adjustable modes for optimized thermal decomposition of specific matrices

Additional information
Automatic closed-loop temperature control and thermoscanning extend the measurement range and enable mercury speciation analysis. Standard warranty: 1 year. Installation, commissioning, support and operator training are available by qualified specialists.
