滴定靛蓝和保险粉

Indigo is a so-called vat dye, which means that it needs to be reduced to its water soluble leuco-form before dying. The reduced form is absorbed into the fibres, and when oxidized back to its blue form it stays within the fibre. Earlier the reduction and dyeing was done with fermentation. Nowadays, the most of the reduction has been done chemically by sodium dithionite.

检测脂肪和油类酸值和游离脂肪酸

The method is suitable for edible fats and oils such as butter, olive, palm or sunflower oil. The acid number is the quantity of base, expressed in milligrams of potassium hydroxide, that is required to neutralize all acidic constituents present in 1 g of sample. The calculation of the % FFA depends on the titrated type of sample.

This method is used fort he quantitative determination of total acidity in fruit juice. Here, the citric acid as the main use as a reference.

检测牛奶或奶制品的酸值

This method is used for the quantitative determination of acidity (acid degree) in milk and milk products. The acidity is calculated either as SH-, Dornic- or Therner degree. The different degree uses different concentrations of NaOH titrant.

检测水的碱度

The alkalinity of water is a measure of its capacity to neutralise acids. The alkalinity of natural water is due to the salts of carbonate, bicarbonate, borates, silicates and phosphates along with the hydroxyl ions in free state. However the major portion of the alkalinity in natural waters is caused by hydroxide, carbonate and bicarbonates with may be ranked in order of their association with high pH values. Alkalinity values provide guidance in applying proper doses of chemicals in water and waste water treatment processes, particularly in coagulation and softening.

检测维生素C（DCPIP法）

This method is used to determine the content of ascorbic acid (Vitamin C) with the specific titrant 2,6-Dichlorphenolindophenol (DCPIP).

检测水样或废水中的游离氯或总氯含量

This method is used for the quantitative determination of Chlorine, Hypochlorite and Chloramine in water and wastewater using the potentiometric or Dead Stop titration method with phenylarisine oxide as titrant. The method is used for chlorine concentrations < 5 mg/L. The endpoint can be detected potentiometric using a combined platinum electrode (recommended) or amperometric using a double platinum electrode.

检测挥发性有机酸（FOS）和总无机碳（TAC）

The determination of the volatile organic acids (FOS) and total inorganic carbon (TAC) or buffer monitor the fermentation process in biogas reactors. Determination of FOS/TAC value is performed as an endpoint titration to two pH endpoint using sulphuric acid. The FOS, TAC and the ratio of FOS/TAC are automatically calculated and displayed.
