AUTOMATIC pH ADJUSTMENT APPARATUS

WIPO Patent Application WO/2013/140560

A1

The present invention pertains to an automatic pH adjustment apparatus, and provides an automatic pH adjustment apparatus which enables short-time preparation of a sample for separation and concentration or which can minimize the contamination factors during the preparation of the sample. In an automatic pH adjustment apparatus (10) according to one embodiment, a pH -adjusting fluid (36) can be jetted in the form of a mist toward the liquid surface of a sample (12) to adjust the pH of the sample (12) to a target level stably with reduced fluctuations in the intensity of transmitted light. Thus, a sample in an amount necessary for separation and concentration can be prepared in a short time. Further, a light source unit (20) and a spectroscope (26), which are used in pH measurement, are located in the outside of a vessel (14), while a jet orifice (28a) of a nebulizer (28) does not come into contact with the liquid surface of the sample (12). In the automatic pH adjustment apparatus (10), as described above, the devices used in pH adjustment do not come in contact with the sample (12), so that the contamination factors during pH adjustment can be minimized.
