Title: Method of quantifying iodine
Inventor: TSURUTA YASUHIRO
IPC: G01N27/62
Filed: 1995-03-14
Abstract: PURPOSE: To quantify iodine with a higher sensitivity and handily by adding a reducing agent and then, acid to a sample solution to restrict the formation of I2 , eventually lowering a memory effect of the iodine in a pretreatment for determining iodine in the sample solution using an induction coupling plasma quantometer ICP-AES or an induction coupling plasma mass spec trograph ICP-MS. CONSTITUTION: Preferably, a reducing agent to be added in a pretreatment of a sample solution is sodium thiosulfate and acid to be used in the pretreatment of the sample solution is hydrochloric acid. The acid is added to the sample solution after the addition of the reducing agent and hence, the quantification of a very small amount of iodine is possible using an ICP-AES or an ICP-MS. Moreover, this can lower a memory effect thereby enabling the quantification of the iodine in the sample solution remarkably, with a higher sensitivity and handily, especially in the use of the ICP-MS.

Filed: 1986-04-09
Abstract: PURPOSE:To obtain a frequency synthesizer with small size and low cost by mixing an instantaneous amplitude data of a triangle function obtained through the integration of an external synthesized frequency setting data at each clock with harmonics of a fundamental frequency. CONSTITUTION:A reference frequency fR generated by a reference frequency oscillator 11 is received by a frequency source 12 to generate a fundamental frequency fo and a clock frequency fc being an integer number multiple of the frequency fR. A digital integration device 15 integrates an external synthesis frequency setting data Nf at each frequency fc and a phase address data corresponding to the phase angle of a sampled triangle function is fed to a triangle function generator 18. Every time the phase address data is received, the generator 18 outputs the instantaneous amplitude data of the triangle function of the corresponding phase angle to a D/A converter 21. The converter 21 coverts the data into a sinusoidal wave signal corresponding to the data Nf, a filter 22 smoothes the sinusoidal wave signal and sends the result to a mixer 14. The mixer 14 mixes the signal from the filter 22 with harmonics of the frequency fo from a high frequency generator 13 and outputs the result via a crystal filter 23. Thus, the frequency is changed at a high speed with a smaller resolution.
