Abstract: PURPOSE:To weigh a liquid by an arbitrary aimed weight with high accuracy by collecting the liquid by a fixed volume which does not exceed the aimed weight and calculating the additional amount of the liquid to be collected required for the aimed weight based on the apparent density of the liquid. CONSTITUTION:During the first operation, the apparent density of a sample liquid is assumed at '1' and the liquid is collected by the volume V1 decided from V1(ml)=WXR1 in accordance with a ratio R1 (R1=0.5 for ordinary liquid) preset to an aimed weight W(g). Then the apparent density D of the liquid is found from D(g/ml)=W1/V1. After finding the density D, the second (additional) volume V2 to be collected of the liquid is decided from V2=W/D-V1. When the liquid is collected by the volume V2 and added to the first collected amount, the liquid can be measured by the aimed volume W. The weighing accuracy can be improved further when the liquid is collected by a volume V3=R2V2 (R2=0.5-0.99) as the second collecting amount and the volume V3 is added to the first collected amount. Then, after measuring the total weight W2, the liquid is collected by a third (additional) collecting volume V4=(W-W2)/D and the volume V4 is added to the first and second collected amounts.

Abstract: PROBLEM TO BE SOLVED: To enable the determining of monomers contained in various polymers with accuracy by utilizing a gel permeation chromatography(GPC) column formed of crosslinked polystyrene of a specific mean particle diameter and a mean pore size. SOLUTION: A GPC column in use is formed of crosslinked polystyrene with a mean particle diameter of 2-4μm, preferably 2.5-3.5μm, and a mean pore size of 10-50Å, preferably 15-20Å. Porous styrene-divinylbenzene polymer spherical particulates are preferable for crosslinked polystyrene forming the column. A styrene-divinylbenzene copolymer, divinylbenzene polymer, ethyl vinyl benzene- divinylbenzene copolymer, etc., are named for styrene-divinylbenzene polymers. By this method, it is possible to accurately determine monomers with π electrons contained in polymers which have monomers with π electrons as constituents with no problems such as the degeneration and thermal decomposition of the column.

Abstract: PURPOSE: To find a new solvent for dissolving polybetaine and to easily measure the distribution of molecular weight of polybetaine by using gel permeation chromatography with formamide as a mobile phase, when measuring the distribution of the molecular weight of polybetaine. CONSTITUTION: Formamide mobile phase is stored in a tank 1 by the gel permeation chromatography method, and the mobile phase is sent to a gel column 4 of porous styrene-divinylbenzene polymeric spherical fine particle by a pump 2 in advance to create a steady state. Then, polyvetyne of a measuring sample is dissolved into the mobile phase to be injected from an injection port 3. The injected sample is separated by each molecular weight while it passes the gel column 4, and is successively let out from the gel column 4 along with the mobile phase, and is detected by a detector 5. Data obtained by the detector 5 are processed by a data processing device 6 and quantitative calculation is conducted. The liquid-feed speed of the mobile phase is preferably generally 0.1-10ml/minute.

Abstract: PURPOSE:To obtain a correct titration value regardless of temperature variation of liquid by calculating a corrected titration amount at a reference temperature based on the coefficient of volumetric expansion and temperature of titration liquid and then subjected the measurement value to temperature correction based on the corrected titration amount. CONSTITUTION:When correct concentration of a titration liquid at a reference temperature is known and an acid value is measured, for example, the titration liquid is added to a liquid to be measured using a delivery means of which delivery volume is detectable. A titration end-point is then determined based a potential variation ratio, a titration curve, etc., and a titration amount is measured at that moment. A titration amount Vts (ml) corrected for a reference temperature is then calculated from the coefficient of volumetric expansion and temperature of titration liquid according to a formula; Vts=Vt/(1+alphat.(Tt-To) [VT: titration amount (ml), alphat: coefficient of volumetric expansion of titration liquid, Tt: temperature of titration liquid ( deg.C)]. Acid value represents the weight (mg) of KOH required for neutralization of acid components contained in 1g of sample and a corrected acid value is determined according to a formula; acid value (mgKOH/g)=Vts.N.56.108/Ws [N: normality of titration liquid, Ws: sampling amount of sample].

Abstract: PROBLEM TO BE SOLVED: To simply and accurately determinate inorganic ion by using a water based gel permeation chromatography (GPC) and using an aqueous solution containing a specific quantity of inorganic salt. SOLUTION: A water-based GPC column is filled with a general purpose high polymer gel, for example polyhydroxymethacrylate gel, silica gel, polyvinyl alcohol gel, etc. Approximately 0.1-1000mmol/l aqueous solution containing inorganic salt, for example NaCl, Na2 SO4 , NaH2 PO4 , etc., it used for its moving phase. The optimum conditions of the inorganic salt concentration are selected according to inorganic ion kinds and coexistent inorganic ion kinds wanted to separate. When the content of the inorganic salt is approximately 0.1mmol/l or less, the separative power of the inorganic ion is deteriorated and when it exceeds approximately 1000mmol/l or more, precipitation of the salt causes liquid leakage from the GPC device, clogging of pipes, etc. This method can simply and accurately determinate the inorganic ion in detergent and surfactant.

Abstract: PURPOSE: To accurately, easily and quickly measure a molecular weight distribution of cationic polymer by utilizing a gel permeation chromatography(GPC) having as a moving phase a formamide solution to which lithium halide is added. CONSTITUTION: In a GPC analysis of cation is polymer, formamide having a high polarity is used as a movement phase and lithium halide is added thereto in order to prevent dissociation of an ionic group in a chain of high polymer. Lithium chloride, lithium bromide, lithium fluoride and lithium iodide can be listed as lithium halide. Lithium bromide having a high solubility to formamide is particularly preferable. A concentration in the moving phase is desired in a level whereby the cation polymer is dissolved and a chromatogram can be reproduced. Thereby, interaction with GPC gel filler does not occur and it is possible to quickly measure a molecular weight distribution of cationic polymer with good reproducibility.
