A dissolved sample can be analyzed for N, P and K within 8 minutes. Finished products and raw materials can be analyzed on the same system. The analysis rate is 30 to 60 samples per hour, depending on the parameter and the system. Several parameters can be analyzed in parallel from the same sample.
MULTITEST METHODS
Specially developed for Fertilizer analysis, these Seal Analytical multitest methods enable you to measure several different parameters with one analytical cartridge or manifold. When changing from one test to another only the reagents and the colorimeter filter need to be changed.
Multitest methods are ideal for laboratories with small to medium workloads, or where some tests are required only occasionally, as there is no need to invest in a separate manifold for each chemistry.
The MT7 and MT8 multitest methods for Fertilizer analysis incorporate a dialyser to eliminate interference from colored samples. Ranges can be varied by changing sample pump tubes.
