The biological element analysis standard materials developed by Weiye Metrology are stable for more than 5 years.
The following reference materials are the first to be developed in China:
· Standard material for elemental analysis of soybean meal, peanut meal, protein powder, pig concentrate feed, chicken concentrate feed
· Standard material for analysis of enoki mushroom, white fungus, lotus root starch, hawthorn and pearl powder
· Standard material for component analysis of onion, rapeseed, jasmine and Henan tobacco leaves
· Standard material for the analysis of inorganic components of red bean powder
The rice developed this time is mainly developed for the main grain-producing areas and characteristic products, and the fixed value elements and standard values have reached a new high level. For example, there are 59 kinds of proposed standard value indicators for the analysis of inorganic components of Liaoning rice flour, 40 standard values and 15 reference values.
