产品介绍 | 规格 | 72 assays (manual) / 720 assays (microplate) / 840 assays (auto-analyser) | | 运输温度 | 环境温度 | | 储存温度 | 短期稳定：2-8℃
长期稳定：详见单独组分标签 | | 稳定性 | >2年(在推荐的储存条件下) | | 分析物 | Citric Acid | | 分析方法 | Spectrophotometer, Microplate, Auto-analyser | | 检测方法 | 吸光度(Absorbance) | | 波长(nm) | 340 | | 信号响应 | 减少 | | 线性范围 | 1.0 to 100 μg of citric acid per assay | | 检出限 | 0.491 mg/L | | 反应时间 | ～5 min | | 产品应用 | Grape juice, wine, beer, fruit juices, soft drinks, tea, dairy products (e.g. cheese), meat, processed meat, vegetable and fruit products, bakery products, paper, pharmaceuticals, cosmetics and other materials (e.g. biological cultures, samples, etc.). | | 方法识别 | Methods based on this principle have been accepted by MEBAK, OIV, EU, ISO2963, AOAC and IFU22 (NOTE: If the enzyme oxaloacetate decarboxylase is present in the sample, some of the oxaloacetate product is converted to pyruvate. Therefore, to ensure citric acid is measured quantitatively, D-lactate dehydrogenase (D-LDH) is employed to efficiently convert any pyruvate produced into D-lactate and NAD+). | | 产品特点 | ·扩展的辅因子稳定性。溶解的辅因子在4℃下稳定保存1年以上。 [·Extended cofactors stability.
