| 1. | Adding a sample changer enables automatic filling to both instruments , cleaning with 2 rinsing agents and drying 若再配上进样器则实现了两台仪器的自动进样、 (用两种清洗剂)清洗和干燥。 |
| 2. | Methods : use head - space automatic injection method , isolating with the nonpolarity flexibility capillary column , calculating with external method 方法:采用外标法顶空自动进样,在非极性弹性毛细管柱上进行分离,效果良好。 |
| 3. | Six - way valve with three loops for auto introduction of sample and flame photometry detector ( fpd ) having satisfactory selectivity for sulfur and phosphorus were used 采用能自动进样的六通阀和对硫磷有选择性的fpd检测器,色谱峰面积与硫化合物含量存在很好的双对数线性关系。 |
| 4. | The dma 5000 measures a sample in 40 seconds , considerably increasing efficiency in your lab . optional sample changers automate filling and cleaning , freeing lab personnel from these routine tasks Dma 5000在40秒内测量一种样品,在相当程度上提高实验室的工作效率。可选配样品转换器,完成自动进样和清洗,解放实验室工作人员执行的这些常规任务。 |
| 5. | The signal collection circuit is used to magnify the signal collected by pressure sensor and send it to a / d card . the stepped motor control circuit is used to drive the automatic servo system to complete continuous test of samples 信号采集电路用于将压力传感器采集的信号放大后送入数据采集卡,步进电机控制电路用于驱动自动进样系统完成样品的连续测量。 |
| 6. | As precise control of incoming sample amount is hard when using microinjector , it is better to use quantitative ring or auto - sampler to take samples when using external standard method to measure content of a certain impurity or main component of the test samples 由于微量注射器不易精确控制进样量,当采用外标法测定供试品中某杂质或主成分含量时,以定量环或自动进样器进样为好。 |
| 7. | The gas sensor array testing system comprises the automated flow - injection apparatus , the data acquisition device and the pc software . sample injection and data acquisition are realized automatically through real time pc control . thereby it assures the reproducibility and reliability of testing 研制成功的气体传感器阵列智能测试系统由计算机实时控制,可以实现测试气体的自动进样和数据采集与处理,提高了测试的重复性和可靠性。 |
