For over 50 years SEAL Analytical (previously Bran+Luebbe/ Technicon) has been the expert in environmental analyzers, fertilizer analyzers and sample preparation instruments. We understand that regulated standard methods are critical, so all SEAL analyzers are supplied with detailed method descriptions including reagent make up, flow diagrams and specific application notes.
Using a Continuous Segmented Flow Analyzer dissolved fertilizer samples can be analyzed for N, P and K within 8 minutes, with finished fertilizer and raw materials able to be analyzed on the same system. Several parameters can be analyzed in parallel from the same sample.
Methods for Fertilizer Analysis
- SEAL Analytical has an extensive library of over 1000 methods.
- AOAC compatible methods.
- Multi-range methods, giving the ability to set up your desired range.
- Dialyzers sometimes used to stop any color interference and/or dilution.
- Methods used with older AutoAnalyzer II and TrAAcs systems are completely transferable to current model AutoAnalyzers.
The Multi-test Manifolds Advantage
- We have Multitest Manifolds specially developed for fertilizer analysis.
- Ideal for labs with small to medium workloads, or where some tests are required only occasionally, as there is no need for a separate manifold for each chemistry.
- Allows you to analyze a large number of different parameters on a single channel fertilizer analyzer.
- Extends any size Continuous Segmented Flow Analyzer to a multiple channel fertilizer analyzer.
- Saves time, lowers your purchase & maintenance costs, and saves space.
- When changing from one test to another only the reagents and the colorimeter filter need to be exchanged.
- The Multitest Manifolds used for fertilizer analysis incorporate a dialyzer to eliminate interference from colored samples.
- Ranges can be varied by changing the sample pump tubes.
