1976年3月在美国举行了一次科学仪器展览会,从展品的概况看,仪器的设计及构造仍在不断改进,但在展览会中并没有出现什么引人注目的新的分析技术。因为多数应用是日常的质量控制,故大部份改进着重于仪器的可靠性、自动化及专用仪器。气体色谱 Varian公司出售3700型色谱仪,仪器包括有双柱单元、新型进样器、鉴定器、恒温箱、程序升温、流量控制及电子设备,据说恒温箱可以控制在室温以上12℃,进样器及
In March 1976, a scientific instrument exhibition was held in the United States. From the general situation of the exhibits, the design and construction of the instrument are still improving. However, there are not any new analytical techniques that attract attention at the exhibition. Because most applications are routine quality control, most of the improvements focus on the reliability, automation, and instrumentation of the instrument. Varian Corporation sells the Model 3700 Chromatograph, which includes a dual column unit, a new sample injector, a detector, a thermostat, temperature programming, flow control and electronics. It is said that the incubator can be controlled at room temperature above 12 ° C And equipment
