DMA-80 evo直接测汞仪采用催化热解-金齐化-冷原子吸收原理,无需任何样品前处理,直接测定样品中汞含量,真正的固体、液体、气体样品直接进样,2~5min得出准确结果。

多年以来汞的准确测定是困扰广大分析工作者的难题之一,汞是常温常压下唯一以液态存在的金属,是在生态系统中能完全循环的重金属,这些特性也使得汞在消解过程中极易损失,分析测试时又常常因记忆效应令实验人员头痛不已。

DMA-80的诞生标志着汞分析检测技术的重大转折。DMA-80因其非常简便快速的操作过程和良好的性能稳定性,,成为直接测汞领域的代表之一,并在上世纪90年代上市后获得了国内外广大用户的高度赞誉,绝大多数国内外标准方法的制定过程中都有DMA-80的身影,在中国已有几千家实验室已经实际体会到DMA-80的良好性能。

  • 固/液/气各种基质样品均可直接进样,无需任何样品前处理过程

  • 无需消耗任何化学试剂,绿色分析,大幅度减少实验室运行成本

  • 2~5 分钟完成样品全部分析过程,提高实验室效率

  • 简单快捷的测量过程,实验人员仅需称样,一键完成测量

  • 避免了汞在前处理过程中的损失和交叉污染,克服了分析过程中的记忆效应

  • 0.0002ng 的检出限,0-30000ng 7个数量级的测定范围,RSD ≤ 1.0% 良好的重现性

  • 稳定性好,标准曲线仅需 3-6个月校正一次

  • 众多国内外权准方法的制定仪器:EPA7473, HJ923-2017, GB5009.17-2021 等"

  • Approximately 2700 – 6000 tons of mercury are released into the at mosphere annually. Once airborne, mercury can travel thousand mile s from its generation point. Eventually, it precipitates onto the l and and water. And once it enters water, mercury is transformed by microorganisms into methylmercury, the most toxic and dangerous for m of mercury. Exposure to high dosage of methylmercury can cause tremors, inabili ty to walk, convulsions and even death. Children exposed to the mercury show a variety of abnormalities such as delayed onset of walking and talking, cerebra l palsy, and slowed neurological reflexes and learning abilities. One of the best indicators of exposure to mercury is testing for co ncentration in hair and blood. The average concentration of mercur y in non-exposed people is about 8 ppb in blood and 2 ppm in hair Mercury has traditionally been measured in hair, blood, tissues, an d urine by CVAAS (Cold Vapor Atomic Absorption Spectrophotometry), which is a time and labor consuming method that relies on complicat ed wet chemistry sample preparation. The DMA-80 Direct Mercury Analyzer from Milestone eliminates the sa mple preparation step, allowing you to rapidly process your samples in m inutes, instead of the hours needed for traditional methods. This r apid testing (which is as accurate, if not more so, that CVAAS) giv es you the answers you need without consuming valuable time and eff ort. Other benefits include: Process both liquid and solid samples – no matter how difficult th e matrix you will get an accurate total mercury reading. The built-in 40-position autosampler allows unattended operation fo r a large number of samples The DMA-80 is portable enough to be stationed where you need it mos t; in your laboratory, in a portable testing van, etc... No chemicals are used in the process so no additional toxic wastes are generated. Completely compatible with US EPA Method 7473

  • 硫柳汞又名乙基汞硫代水杨酸钠,是一种含汞有机化合物,以重量计含汞49.6%。是一种在疫苗中广泛使用的防腐剂。由于是汞制剂,硫柳汞的加入量必须严格控制,以防止对人体造成毒害,所以我国药典规定对生物制品(疫苗)中硫柳汞含量要进行测定,以确保生物制品质量符合国家标准。本文参考《中国药典》2020版3115硫柳汞测定法,通过DMA80快速测定生物制品中的硫柳汞含量。相对标准偏差RSD为0.68~0.91%,加标回收率为98.6~98.8%。结果表明,该方法具有操作简单、快速高效等优点,可用于生物制品中硫柳汞含量的快速测定。

  • 在日常生活中,各种类型的药物可以满足人们治病或者保健的需要。然而,并非所有药物中的物质含量都对人体无害。很多药物中都存在重金属物质。重金属物质可能来自于药品原材料辅料及生产设备,也可能来自药品存储及运输等过程。世界各地的监管机构负责确保药品的有效性与安全性。为实现这一目标,必须对潜在有毒和有害的污染物(包括元素杂质)进行鉴定,并规定患者允许暴露的最大浓度。因此,在药物分析检测中,如何有效地对药物中重金属进行检查是医药研发人员一项重要的工作。
