Discrete analysers
When flexibility and ease of use are important to your lab, a discrete analyser is a good option to consider. It gives the operator the freedom to choose which parameters to run on each sample along with features such as reagent level sensing, automated dilutions and sample blanking. We have discrete analysers for small, medium and large laboratories.
More information
Discrete analysers are specialised instruments that offer high precision with low sample consumption. These analysers are ideal for laboratories that need to handle multiple samples simultaneously, with applications in water analysis, environmental monitoring and food control. Automation and versatility make them an indispensable tool for efficient and reliable laboratory analysis.
✅ Flexibility - select the parameters to be analysed with a simple push of a button in the software
✅ Automation - automatic calibrations, dilutions, checks and washing of the instrument make work easy
✅ Our instruments are designed for environmental analysis with robust washing functions and an optically clean 10 mm quartz glass cuvette.
How does it work?
Discrete analysers, at their core, are technological marvels that enable fast and accurate chemical analyses by automating the process. Here's a detailed look at how they are built and work:
✅ Pipetting and dispensing: This is achieved by a 1000 μL dilution syringe, 3-way valve, stainless steel sample needle and specific tubing. The system is constantly filled with deionised water, designed so that samples or reagents do not come into contact with the syringe and valve.
✅ Sampling: First, reagents are drawn into the Teflon tube. Then samples are collected by the sample needle, with the level detection system activated to ensure correct reagent volume.
✅ Protection against contamination: Air gaps are created between system water, reagent and sample, preventing contamination. In addition, the sample needle has its own cleaning device to prevent cross-contamination.
✅ Mixing and reaction: Samples and reagents are actively mixed in a reaction well heated to 39°C, ensuring constant reaction conditions. Users can add up to four reagents per sample at specified times.
✅ Absorbance reading: After the set reaction time, the reaction mixture is transferred to a cuvette via a peristaltic pump. The correct filter is selected and absorbance readings are taken. After each analysis, the cuvette is thoroughly cleaned to avoid carry-over.
✅ Data management: Finally, absorbance data is used to calculate the results based on the calibration data. The results can be presented in customised HTML reports or exported as .csv files for further analysis.
Combining advanced technology with careful design, discrete analysers from SEAL Analytical give laboratories the ability to perform multi-parameter analysis with precision and efficiency.
Areas of use
Discrete analysers are a core component of modern chemical analysis. Their ability to automate, speed up and increase the accuracy of analyses makes them indispensable in a wide range of applications:
✅ Colorimetric analyses: Discrete analysers specialise in colorimetric analysis and can handle water-based solutions such as drinking water, wastewater, industrial waste, leachate and much more.
✅ Nitrogen measurements: Whether it's ammonia, nitrates or other nitrogen compounds, these analysers can deliver accurate results in a short time.
✅ Phosphorus measurements: With the ability to detect phosphorus in various forms, from organically bound to inorganic, the analysers provide a comprehensive picture of phosphorus levels in a sample.
✅ Soil extract: For the agricultural sector and environmental science, the ability to analyse soil samples is essential. Discrete analysers can isolate and measure specific chemicals and nutrients from soil extracts to provide insights into soil quality and health.
✅ Water samples: From drinking water quality to trace elements in wastewater, the analysers provide accurate data that is crucial for safety and regulatory compliance.
✅ Digest samples: Especially in the case of Tot-N and Tot-P, discrete analysers can process digested samples to provide a complete analysis of nutrients and pollutants.
