AQ400

The AQ400 Discrete Analyzer is a high-performance, bench-top analyser from SEAL Analytical, specifically designed for environmental laboratories requiring automated and reliable nutrient analysis of water, wastewater and soil samples. With a focus on speed, capacity and flexibility, the AQ400 offers improved reproducibility and is ideal for analytical laboratories requiring high throughput and minimal maintenance.

The AQ400 is designed to meet the high demands for analytical accuracy in environmental samples. It is equipped with advanced robotics for fast sample handling and can handle a large amount of samples with high precision. The system is optimised to reduce the risk of cross-contamination and offers several automation features to simplify operation.

Features and benefits
✅ Used as a stand-alone spectrophotometer: Ideal for COD analyses and other specific applications.
✅ High throughput and quiet operation: the AQ400 handles a large number of samples without disturbing noise levels.
✅ Advanced robotics: Provides fast sample preparation per hour for increased efficiency.
✅ No cross-contamination: Thanks to the optically clean and inert glass cuvette recommended by the EPA.
✅ Low detection limit: Support for longer optical path lengths and automatic blanking function for improved sensitivity.
✅ Programmable tests per sample: Optimised to reduce the overall time of the analysis system and can handle up to 10 working standards for the calibration curve.
✅ Fully automated unattended operation: Ideal for night runs that streamline laboratory work.
✅ Environmental standards: ISO & USEPA approved methods for both wastewater and drinking water and UKAS methods according to the UK Blue Book.

Applications
The AQ400 handles a wide range of methods and analytes, important for environmental laboratories analysing water, wastewater, soil, and the like. Common applications include:
✅ Alkalinity
✅ Ammonia
✅ Chloride
✅ Cyanides
✅ Nitrate/Nitrite
✅ Phenols
✅ Phosphate (ortho)
✅ Total phosphorus
