三菱化学库仑法试剂-AKX/AXI/CXU Coulometric Reagents
库伦法试剂
AQUAMICRON ®(6种:AXI、AX、AX01、AS、AKX、CXU、FLS)是用于库仑法的卡尔费休试剂(检测水分用试剂)。【AX01跟AX是同一种,只是包装不一样,因此属于同一种】
◆原理
如下面化学反应公式1所示,卡尔费休法使用卡尔费休试剂测定水分含量,该试剂定量地、有选择性地与水发生反应。卡尔费休试剂的组成成分是碘、二氧化硫、盐基和溶剂(酒精等)。
I2+SO2+3Base+ROH+H2O→2Base•HI+Base•HSO4R •••••• (1)
卡尔费休法里有库仑法和容量滴定法。
库仑法

往以碘化物离子、二氧化硫、盐基和溶剂(酒精等)为主要成分的电解液里添加试样。如公式2所示,通过电解氧化作用产生碘,直接与卡尔费休试剂发生反应。
2I” – 2e→I2 ·····(2)
按照法拉第定律,碘的产生与电量成正比。因此,能够从电解氧化所需的电量中求得含水量。
1mg的水=10.71库仑
如图所示,需要两种类型的库伦试剂:一种是阳极电解液,置于电解池的阳极室中;另外一种是阴极电解液,置于电解池的阴极室中。库仑试剂无需估定,而且阳极液可以重复使用。

日本三菱化学卡尔费休试剂使用小知识

日本三菱化学卡尔费休试剂使用小知识

目录
如何进行电终点检测法?
如何选择容量滴定法和库仑法?
如何确认水分汽化装置的准确性?
吡啶型(旧产品)和无吡啶型的区别在哪里?
为什么抑制强碱性胺的干扰反应时,需要使用水杨酸?
为什么滴定终点后的溶剂放置一段时间后颜色发生了变化?
◆如何进行电终点检测法?
  现在市面上售卖的滴定装置(容量滴定法、库仑法)采用的是电流控制电压检测法(恒流极化电压检测法)。这个方法通过在双铂电极中输出1~30μA的恒流,检测在两极之间生成的电圧(极化电压),从而测出终点。滴定溶液中含有较多水分时,会显示300~500mV的电压(极化电压)。这个电压会因为溶剂的种类、试样不同而变动。一般来说,像烃这样的电导率低的物质则会显示高电压。
进行卡尔费休滴定法操作,接近终点时,电压会突然下降到10~50mV。容量滴定法的话,当电压持续一段时间时,可判定其为终点。市面上滴定装置的时间大概是30~60秒。库仑法的话,需要先设定终点的电压,低于此电压时可判定为终点。
◆如何选择容量滴定法和库仑法?
请根据下文的标准作出判断。
(1)活用库仑法的特征
  由于不需要卡尔费休试剂(滴定剂)的标定操作,无需滴度的管理,作为日常分析来说省了不少步骤,非常便利。
(2)通过含水量来选择
  含水量大约在1%以下的时候,请使用库仑法。
  特别是,用ppm的精度去定量ppm级含水量时,库仑法更有优势。
  当含水量超过约1%的时候,虽然也可以使用库仑法,但是由于需要取少量的试样,称量的误差将会影响分析值,所以一般都会采用容量滴定法。
(3)是否有电极反应
  苯胺类,胺类,一部分的酚类等电极反应物质不适合使用库仑法。请使用合适的脱水溶剂进行容量滴定法操作。
(4)不溶于电解液的固体物质
  由于不溶于有机溶剂的固体物质会阻塞电极和隔膜,导致电流效率低下,请不要使用库仑法。这种情况请使用合适的脱水溶剂,选择容量滴定法或水分汽化法进行操作。
◆如何确认水分测定仪的准确性?
  组装水分测定仪后,试样中汽化的水分会通过干氮气的加热管、吹管,被脱水溶剂(或电解槽中的电解液)吸收,但水分到底有没有被准确地收集呢。确认水分的收集率(回收率)有以下3种方法。
(1)使用水
   一般来说,使用水是最简单的方法。使用微量注射器(容积10μl)把5或10μl(5或10mg)的水直接注入试样管里。
(2)使用二水酒石酸钠(理论含水量15.66%)
  需要使用预先经过105℃干燥的二水酒石酸钠。
(3)使用玻璃毛细管
  操作简单,可以确认1000μg前后的收集率。玻璃毛细管常用于生物领域,容积非常准确。毛细现象使其可以简单地吸取指定容积的水。
◆吡啶型(旧产品)和无吡啶型的区别在哪里?
  无吡啶型的意思是,把作为卡尔费休试剂成分之一的盐基的吡啶换成其他胺。由于吡啶具有特异性气味,不利于操作。因此把吡啶换成高沸点的液体或固体胺,使吡啶的气味消失是无吡啶型的特点。
  除了盐基之外,无吡啶型和旧产品的成分基本一致,因此需要遵从同样的安全使用准则。现已得到证实,无吡啶型的性能和旧产品的吡啶型几乎一样。
  卡尔费休试剂的反应速度是根据滴定液的pH值、二氧化硫浓度、有机溶剂的种类、以及添加试样的量和矩阵的变换而变动的。因此不可以一言断定哪个产品的反应速度更快,这需要根据具体情况具体分析。
◆为什么抑制和强碱性胺的干扰反应时,需要使用水杨酸?
  对强碱性胺(pKa值在9以上)直接进行卡尔费休滴定法的话,会出现终点稳定性差、分析值升高等的干扰反应。为抑制这种干扰反应,需要进行酸的中和前处理。以前是使用乙酸,但是有着容易发生酯化反应、一般含有较多水分等的缺点。经研究讨论后,开始使用水杨酸并取得了良好的结果。使用水杨酸的优点如下所述。
  ①酯化反应在通常的滴定操作中不受认可。
  ②可把甲醇用作滴定溶剂,得到卡尔费休反应的良好结果。
  ③水杨酸的含水量低。
  虽然水杨酸是固体,会对操作造成不便。但是事先称量约10g水杨酸,放进滴定瓶中,接着添加50ml的脱水溶剂GEX(或者MS),搅拌溶解,即可简单地完成准备。10g的水杨酸可以测至70mmol的胺。
◆为什么滴定终点后的溶剂放置一段时间后颜色发生了变化?
  完成滴定终点之后的溶液放置一段时间后,会出现颜色变黄,再次消耗卡尔费休试剂的情况,或者相反地,变成滴定过量似的红褐色。原因是湿气从外部混入,或者是溶液中含有的碘化物离子与紫外线或氧生成游离碘。

AQUAMICRON® 卡尔费休试剂
blob.png
卡尔费休法使用卡尔费休试剂测定水分含量,该试剂定量地、有选择性地与水发生反应。卡尔费休试剂的组成成分是碘、二氧化硫、盐基和溶剂,如酒精。
这种方法可用于库伦及容量滴定系统。该法基于卡尔费休试剂与水反应的碘定量法,如果试样中含有能够与碘反应的物质或者某些通过碘化物氧化而产生碘的物质,结果出现误差。
即使某些物质不能直接滴定,其水分还可以用间接法加以测定,如水汽化法。

Suitable for detection of total antioxidant capacity in serum and food extracts. For research use only.
Antioxidant assay:

Oxidative stress plays on important role in various diseases and aging. The control of oxidative stress is expected to be useful to prevent diseases and aging.Oxidative stress is caused by the imbalance between reactive oxygen species (ROS) and antioxidant defense system. For accurate assessment of oxidative stress, measurement of ROS, oxidative damage and antioxidant activity may be essential. Recently, antioxidants as functional foods which scavenge ROS attract a great deal of attention.
Principle of this assay:

In the PAO assay kit, an easy and convenient method to measure antioxidant capacity is provided. Utilizing the reduction of cupric ion (Cu++ to Cu+), antioxidant capacity of samples can be detected in 5 minutes. Samples are mixed with Cu++ Solution. Cu++ are reduced by antioxidants to form Cu+. Reduced Cu+ react with Chromatic Solution (Bathocuproine) , and can be detected by absorbance at wavelength 480 to 490 nm. Antioxidant capacity can be calculated from the Cu+ formed. PAO can detect not only hydrophilic antioxidants such as Vitamin C, glutathione, but also can detect hydrophobic antioxidants such as Vitamin E. Applicable for assessment of total antioxidants of serum, foods and beverage samples.
Specifications:

Method: Colormetric assay(detection: 480 – 492 nm)
Assay range: 21.9 – 4378 碌mol/L (cupric ion reducing power)
Format: 96 wells
Storage: Room temperature (10 – 25掳C)
Applications: Human and animal serum samples, foods and beverage samples.
Required but not provided: A micro plate reader (measuring wavelength 492 nm)
Pipettes and pipette chips
Plastic test tubes
Distilled water
NaOH, HCl solution and pH meter (Not required if standards are prepared with distilled water only).

 
Content of this kit: 试剂盒组成

Standard (Uric acid powder): 1 vial
Sample diluent: 1 bottle
Cu++ solution: 1 bottle
Stop solution: 1 bottle
Micro titer plate: 1 plate (96 wells)

Assay procedure:

1) Prepare 6 levels of standards by diluting 2mM uric acid.
2) Please prepare plastic test tubes for 6 levels of standards and each sample. Pour 390 碌L of Sample Diluent, and add 10 碌L of standards or diluted samples.
3) Pour 200 碌L of mixture to Micro titer plate. Use 200 碌L of Sample Diluent for blank well.
4) Read absorbance at 490 nm (as READ1).
5) Add 50 碌L of Cu++solution to each well, mix gently, and incubate at room temperature for 3 minutes.
6) Add 50 碌L of Stop solution, mix gently, and read absorbance at 490 nm (as READ2).
7) Please draw standard curves by plotting the difference of absorbance readings (READ2 – READ1) as vertical axis, and concentration of uric acid standards (mM) as horizontal axis. Calculate the corresponding uric acid concentration of samples. Multiply corresponding uric acid concentration (mM) of samples by 2189, to estimate antioxidant power (碌mol/L).
1mM of uric acid = 2189 碌mol/L (copper reducing power)

Dityrosine (DT) ELISA kit.
Suitable for urine samples. For research use only.
A novel biomarker for protein oxidation

Tyrosine is one of the major targets of protein oxidation, and until today various tyrosine derivatives such as nitrotyrosine, dityrosine and halogenated tyrosine depending on the type of free radicals. DT is a tyrosine dimer derived from tyrosyl radicals which is formed by reactive oxygen species (ROS), metal-catalyzed oxidation, ultraviolet irradiation, and peroxidases. DT have been found in atherosclerotic lesions, and lipofuscin of pyramidal neurons of aged human brains. Dityrosine is one of the specific biomarkers for protein oxidation.
Recently, dityrosine is reported to exist also in urine samples. It is expected that DT may be a novel protein oxdation marker, which is non-invasively detectable. DT ELISA kit is designed for quantitative measurement of DT especially in urine samples.
试剂盒组成:

Samples: Urine

Biomarker for early stage of lipid oxidation
Oxidative damage of lipids caused by reactive oxygen species (ROS) play an important role in some diseases, lesion of cell functions and aging. Aldehydes such as malondi-aldehyde (MDA) and 4-hydroxy-2-nonenal (4-HNE) have been reported as one of the advanced lipid peroxidation products. But recently in the earlier stage of lipid peroxidation, 13-hydroperoxyoctadecanoic acid (13-HPODE) is found to be covalently bound to proteins1). Hexanoyl-Lysine adduct (HEL) is a novel lipid hydroperoxide-modified lysine residues. HEL is formed by oxidative modification by oxidized omega-6 fatty acids such as linoleic acid or arachidonic acid. HEL may be a useful biomarker for initial stage of lipid peroxidation.Monoclonal antibodies and ELISA kit have been developped, and HEL can be detected in oxidatively modified LDL, in human atherosclerotic lesions, human urine and serum. It is also reported that HEL is formed in rat muscle during exercise, and the formation is prohibited by antioxidants such as flavonoids.
由活性氧(ROS)引起的脂质氧化损伤在一些疾病、细胞功能损害和衰老中起重要作用。醛类如丙二醛(MDA)和4-羟基-2-壬烯醛(4-HNE)已被报道为先进的脂质过氧化产物之一。但最近在脂质过氧化的早期阶段,发现13-氢过氧十八烷酸(13-HPODE)与蛋白质共价结合。己酰-赖氨酸加合物(HEL)是一种新的脂质氢过氧化物修饰的赖氨酸残基。HEL是通过氧化的omega-6脂肪酸(例如亚油酸或花生四烯酸)的氧化修饰形成。HEL可能是脂质过氧化初始阶段有用的生物标志物。现在我们已经开发了HEL单克隆抗体和ELISA试剂盒,并且可以在氧化修饰的低密度脂蛋白(LDL)、人动脉粥样硬化病变、人尿液和血清中检测HEL。另据报道,大鼠肌肉在运动期间形成HEL,并且通过抗氧化剂(如类黄酮)是禁止形成的。
