6. Reagents for Colloidal Titration
The colloidal titration method is titrimetry for simply determine the polymer electrolyte by titration. In general, colloids having positive or negative electric charges stoichiometrically react with colloids having opposite electric charges and form a sparingly water-soluble precipitation. In the event that the positive colloid is determined by the use of this principle, the solution is titrated with the normal solution of potassium polyvinyl sulfate (PVSK) having a negative electric charge. Toluidine blue of the indicator is a basic dyestuff having -N2 Hand is not absorbed by the positive colloid, showing an original blue color, but when it encounters with a negative colloid, toluidine blue is immediately absorbed and assumes a red-purple color. The equivalent point of the reaction is, therefore, able to be simply and highly accurately detected.

8. Karl Fischer Reagents [ Mitsubishi Chemical Corp.]

Karl Fisher method uses Karl Fischer reagent, which reacts quantitatively and selectively with water, to measure moisture content. Fischer reagent consists of iodine, sulfur dioxide, a base and a solvent, such as alcohols. This method can be used in both coulometric and volumetric titration systems

<Reagents for Coulometric Titration>
There are two types of coulometric reagents: the anolyte (generating solution), which is placed in the anode chamber of the electrolysis and the catholyte (counter electrolyte), which is placed in the cathode chamber. There are also special anolyte for use with ketones, lower carboxylic acids and silicone oils. AQUAMICRON® can be used in coulometric moisture measurement systems sold by various companies, and it has a worldwide reputation for excellent performance.

D. Reagents for Atomic Absorption Spectrochemical Analysis
1. Reagents for Atomic Absorption Spectrochemical Analysis
Atomic absorption spectrochemical analysis is used for determination of trace metals. Because of high sensitivity, high selectivity, and easy operation, atomic absorption spectrochemical analysis is an important analysis method of heavy meals in water, soil, and biological samples. As reagents used for atomic absorption spectrochemical analysis, high-quality pretreatment reagents of acids, alkalis, etc. and metal standard solutions with extremely little content of heavy metal impurities are readily available.

◆Each product guarantees the content of various metallic impurities at the ppt level.
◆In order to maintain the ppt-level quality for using fluororesin (PFA) containers (extra-pure water uses high-density polyethylene containers), PFA containers thoroughly cleaned before filling is used.
◆Double plastic bag packing used: Because single plastic bag (inside) packing is performed in the clean room, the reagents are able to be carried into the clean room as it is.
◆Inspection report attached: Impurity metal analysis by ICP-MS and FL-AAS is performed, and the analysis results are attached to the product.

Q. Wetting Tension Test Mixtures
■ Wetting Tension is c
The ability of plastic films to retain inks, coating, adhesives, etc ., is primarily dependent on the character of their surfaces, and can be improved by one of several surface-treating techniques. These techniques have been found to increase the wetting tension of a plastic film surface in contact with mixtures of solvents. It is therefore possible to relate the wetting tension of a plastic film surface relates to its ability to accept and retain inks, coatings, adhesives, etc .
The condition with water drops placed on the surface is not defined to be wet (Fig. 1). To let the surface get wet with a liquid with strong surface tension as in the case of water, the film surface must have the property to blend into water (high polarity). Conversely, with the solvent with weak surface tension as in the case of organic solvent, the film surface gets wet even if the film surface has a property to repel water.
Consequently, when plastic film is coated with paint, provided with coating, or bonded, it is important to know the wetting tension of plastic film. (Prescribed in JIS K6768.)
■ Principle

A series of mixtures of solvents of gradually increasing surface tension are applied to the surface of the plastic film until a mixture is obtained that just wets the film surface. The wetting tension of the surface under test is approximately by the surface tension of this particular mixture.

■ Wetting Tension Test Mixture

36 kinds of test mixtures of graduated wetting tension are available for wetting tension test.

■ Procedure

A cotton-tipped stick is used for spreading the test mixtures and the liquid shall be spread rapidly over an area of at least 20 cm2. The quantity of liquid shall be such that it forms a thin film without pools. Impregnate the mixture and apply only one coat to the film in the lateral direction. The amount of the liquid applied exerts great effect on the accuracy of the test, to which care must be taken.

○ In the case of excess application

The liquid film does not break from the film inside but shrinks from the surrounding, and forms a large liquid drop (large measurement value results).

○ In the case of application of an appropriate amount

Breakage of coated liquid film simultaneously occurs not only from the surrounding but also the center part of the film.

○ In the case of application of excessively small amount

In the case of application, breakage of liquid film occurs in the direction where the cotton-tipped stick is moved and application irregularity is formed (small measurement value results).

■ How to determine

Observe the liquid film of the test mixture under glancing illumination and note the time taken for the continuous liquid film to break up into droplets. If the liquid film holds together for more than 2 seconds, repeat the test on a new specimen with a mixture of the next higher surface tension, until the liquid film breaks up in less than 2 seconds. If the liquid film holds for less than 2 seconds, proceed to lower surface tensions until the film persists for 2 seconds. (Fig. 2)
