Foss™ Tecator™ Kjeltec™ 8400 Analyzer Unit

Description

Automatic distillation and approved colorimetric titration for analysis of Kjeldahl nitrogen/protein, ammonium-nitrogen, TKN, Direct Distillation (DD), and volatile acids/bases.

Standard Features

• Automatic distillation procedure includes sample dilution, alkali and receiver addition, distillation, titration, calculation, reporting and tube draining
• Optional 20 or 60 place sample changer allows for fully unattended operation
• Complete PC control of all registration and reporting through optional data management software
• Alarms for reagent availability
• Accurate bellow pumps; high-precision refillable, interchangeable burette
• Intelligent cooling water control adjusts the flow according to temperature minimizing water consumption and costs
• Distillate temperature sensor automatically shuts down unit if risk exists of inaccurate results

Design

• Built-in variable steam generator for deionized or tap water
• Alkali/water/receiver/waste tanks with level sensors
• Surfaces exposed to reagents are made of corrosion-free, chemical-resistant dyed plastic materials
• Self cleaning titration vessel

Safety Features

• Sensors for: 1) tube in place, 2) automatic safety door, 3) reagent level, 4) water level and 5) overpressure for steam generator
• SAfE™ (Steam Addition for Equilibration) technology improves safety by incorporating its own mixing procedure, reducing exothermic reaction between alkali and acid and making manual predilution of samples unnecessary
• A fast tube draining system removes the need for handling hot reagents after distillation
• Safety door and drip tray can both be easily removed for cleaning

Specifications

• Analysis time: 3.5 min. at 30mg nitrogen (6.5 min. at 200mg nitrogen)
• Distillation capacity: approximately 40mL/min
• Measuring range: 0.1—200mg nitrogen
• Reproducibility: ±1.0% relative (including the digestion step)
• Recovery is greater than 99.5% at nitrogen levels between 1 and 200mg
