毛细管电泳(CE)技术具有分离效率高、分析速度快、受基质干扰小、试剂样品消耗少且对环境友好等优点,在阳离子分析领域潜力巨大。该法可用于测定各种饲料、复合饲料、饲料、预混料、饲料添加剂和植物、动物、矿物原料的无机阳离子(钾、钠、镁、钙离子)的质量浓度。检测波长在254nm或267nm处,该测定不受其它无机阳离子(Ba, Li, Sr, Mn, Fe)的存在所影响。
The method 1 is used for the determination of the mass fraction of total inorganic cations (ammonium potassium, sodium, magnesium, calcium) in all types of feedstuffs, compound feeds, fodders, premixes, fodder additives, and feed raw materials (of plant, animal, and mineral origin) by capillary electrophoresis.
The measurement method is based on capillary zone electrophoresis with indirect UV detection at the wavelength of 254 or 267 nm.
The measurement range for the components is 0.01–40% for the sample weight of 100 mg.
The determination is not hindered by the presence of other inorganic cations (Ba, Li, Sr, Mn, Fe) in the concentrations that are typical for this type of samples.
The CAPEL capillary electrophoresis system is used in measurements. Data acquisition, collection, processing and output are performed using a personal computer running under WINDOWS® XP/7/8/10 operating system with installed dedicated software package ELFORUN.
