Nitrogen analyzer rapid MAX N exceed PLUS

proteinlaboratoryfor the food industry

Overview The rapid MAX N exceed PLUS is a nitrogen and protein analyzer based on the Dumas combustion method. Designed for continuous unattended 24/7 operation, it delivers nitrogen and protein results in approximately 5 minutes per sample. The system accepts a wide range of matrices and sample weights up to 5 g / 5 ml, and supports helium or argon as carrier gas to optimize cost per sample.

Highlights

• Upright reusable steel crucibles handling liquids, semi-liquids and solids up to 5 g / 5 ml
• 90-position autosampler reloadable during analysis for sample prioritization
• Typical analysis time ~5 minutes with self-optimizing parameters by element content and weight
• Tool-free maintenance with slide-out furnace and clamp connections

Features

• Thermal Conductivity Detector (TCD) with catalytic post-combustion for complete nitrogen recovery
• Smart instrument control software with LIMS integration and optional 21 CFR Part 11
• Reduced consumable usage via EAS REGAINER® technology and option to operate with argon
• Reloadable autosampler enables high throughput with fewer calibration and maintenance events

Typical sample types

• Liquids: milk, beer, soft drinks, juices, soy sauce
• Semi-liquids: yogurt, mayonnaise
• Solids: meat, cereals, flour and other agricultural and food products

Product details
