在发生氢化物-原子荧光测定中,现行的进样方法大都是采用医用注射器,每次分取液量全凭人工控制,定量重现性较差,从而影响了测定结果的可靠性。为此进行了改进,新装置经使用效果良好。一、制作方法及工作原理将定量加液器塑料盖沿圆孔边缘锯掉,保留铁杆及圆孔部分。然后把10毫升注射器套入圆孔卡紧。在 In the occurrence of hydride - atomic fluorescence determination, the current injection methods are mostly used medical syringes, each dispensed full manual control, quantitative reproducibility is poor, thus affecting the reliability of the determination results. This has been improved, the new device by the use of good results. First, the production methods and working principle Will be quantitative dosing plastic cover cut along the edge of the hole, leaving the iron and the hole part. Then put the 10 ml syringe into the circular hole and fasten it. in
