摘要： PROBLEM TO BE SOLVED: To provide a method for stably and accurately measuring the amount of hydroxyhydroquinone in a coffee sample, or the like. SOLUTION: In the measurement method of the amount of hydroxyhydroquinone in a coffee drink or food containing coffee extracts, an acid is added to the coffee drink or the food containing coffee extracts and pH is adjusted to 5 or smaller, and a sample solution to which a chelate agent is added is subjected to liquid chromatography.

摘要： PROBLEM TO BE SOLVED: To provide a method of exactly and rapidly evaluating the effectiveness (hair quality improving effect) as a hair quality improving agent of a test agent from information on hair lipid composition before and after use of the test agent. SOLUTION: In this method of evaluating the hair quality improving agent, a sample prepared from a hair root part of hair or a hair bottom part near the scalp before and after use of the hair quality improving agent is separated and detected by a liquid chromatograph-mass spectrometry, the composition information on hair lipid molecules is obtained, and the composition information on hair lipid molecules before and after use of the hair quality improving agent is associated with the hair quality improving effect of the hair by use of the hair quality improving agent.

摘要： PROBLEM TO BE SOLVED: To provide a trace solid sample treating instrument capable of bringing a trace solid sample into contact with treatment liquid for a long time, and separating easily the solid sample from the treatment liquid after contact. SOLUTION: The trace solid sample treating instrument 10 includes a holder 20 having a capillary part 21 capable of holding a trace solid sample 40 inside, and a storage 30 capable of sealing and storing the holder 20. The trace solid sample 40 is installed inside the capillary part 21 of the holder 20 in the trace solid sample treating instrument 10, and the holder 20 in which the sample 40 is installed is stored inside the storage 30, and the treatment liquid is filled into the storage 30 before or after storage or simultaneously with the storage, then, the storage 30 is sealed, and the sample 40 is treated by the treatment liquid.

摘要： PROBLEM TO BE SOLVED: To obtain a simultaneous analytical method in which the composition of a surface active agent is qualitatively and quantitatively analyzed with good accuracy without executing a pretreatment by combining a high-performance liquid chromatograph with an evaporation light scattering detector, and adopting a reversed-phase gradient elution method in which a volatile salt in a quantity sufficient to hold an ionic surface-active agent is contained in a solution. SOLUTION: A gradient elution method by a mixed solvent of two or more kinds of water/organic solvents which contain a filler for reversed-phase chromatography as a column filler and which contain a volatile salt as an elute is used. The eluate which is eluted from a column is changed into a mist by a nebulizer while it is mixed with a compressed gas, the mist is humidified, a volatile compound is removed, and a nonvolatile compound is detected by using an evaporation light scattering detector which can detect it. The identification of a peak on an obtained chromatogram is performed in such a way that the holding time indicated by the peak is compared with the holding time indicated by a single-chain-length standard compound available on the market or with a synthetic compound.
