SAMPLE HOLDER FOR PLATING LIQUID ANALYZING INSTRUMENT

摘要

PURPOSE:To make possible stable measurement with a sample holder for online analysis of many kinds of plating liquids by providing a window for measurement to the front face of each holder and a pipe for flowing in and out of the plating liquid and an air vent pipe for maintaining the specified pressure in the sample holder to the rear surface. CONSTITUTION:A cap 4 having the window is provided via an O-ring 5 to the front face of each sample holder 1. A film 6 for X-rays is adhered to the window. The components of the plating liquid are measured by irradiating the X-rays to the window. The plating liquid entering from a back liquid tube 9 rises in the holder 1 and is discharged from a waste liquid tube 10. An air vent tube 11 is attached upward to a union 8 to vent the air in the plating liquid and to suppress the increase of the pressure in the holder 1. The disposition of the holders 1, an X-ray generator 12 and an X-ray detector 13 is positionally changed by moving laterally the holders 1, by which the measurement of many kinds of the plating liquids is made possible.
