在容量分析中,滴定管的使用直接影响到分析结果的准确性,用滴定液电子自动计量装置。进行滴定液消耗电子自动读数,易于操作,效果很好,具有一定的推广价值,现介绍给同行们参考。一、装置部件性能。见图 1.受滴传感器: 用两根长约4 cm不锈钢丝(或针灸针),其一端焊细导线,另一端弯成“L”型。将连线端用环氧树脂类粘合胶固定在一长约5 cm的鳄鱼夹背侧外1/3处。(双导线均须与夹子绝缘),使用时将该受滴传感器夹在玻璃
In volumetric analysis, the use of burets has a direct impact on the accuracy of the analytical results, with a titration solution electronically automated metering device. Titration consumption of electronic automatic readings, easy to operate, the effect is good, with a certain promotional value, are introduced to their colleagues for reference. First, the performance of the device components. See Figure 1. Drop Sensor: Use two 4 cm stainless steel wires (or acupuncture needles) that have a thin wire at one end and an “L” shape at the other end. The connector end with epoxy adhesive glue fixed in a 5 cm long crocodile clip on the back 1/3. (Both wires must be insulated from the clip). When used, clip the drop sensor to the glass
