一台气相色谱仪是通过检测分离的组分来分析气体或挥发性液体。组分的不连续分离和准确识别，以及成分无干涉的测量是气相色谱仪的绝对优点。正是由于这些优点，气相色谱仪广泛应用于许多工业领域。
YOKOGAWA制造两种型号的GC1000型过程气相色谱：GC1000S/E/C型（恒温箱型）和GC1000D/T/W型（程序升温型）。GC1000S/E/C型能分析从室温到对应于各组分的汽化点的温升过程的气体和液样。GC1000D/T/W型通过使用类似于实验室气相色谱仪的毛细管柱来完成高分离度的分析。 TDLS200采用独特的峰面积积分法且具备可调谐二极管，无需采样装置，根据气体近红外吸收理论，可以在高温高压等恶劣工艺环境下实现快速、精确的测量，还可以在腐蚀性、刺激性及高粉尘浓度等恶劣条件下进行测量气体浓度。 DM8振动式液体密度计的开发基于VD6取得的经验，是高度可靠、功能丰富的仪表。它采用了最新的计算机技术，集合了多种传感器技术。其转换器结合微处理器，将传感器频率信号直接转换为密度值进行显示。该仪表具有多种功能，如一键标定、自诊断和数字输出(RS-232C)等。

system structure
The Freelance 800F process control system is divided into operator levels
and process control level. The operator level contains controls for operation and display.
Archiving and logging, trending and alarming functions. Controller executes open loop
and closed loop control function.
Freelance 800F DigiVis Operator Level
DigiVis operator stations use PC hardware, either standard commercial
Business PCs can also be industrial-grade PCs and run on Micro-
under soft Windows operating system. DigiVis supports dual-screen display operation
operating technology, that is to say, two operations can be performed using one PC
station and operate with a mouse and a keyboard.
Operator level can install one engineering station and several operators

Mode. Usually, we can use portable devices such as notebooks to
The system is now configured in the office and on site. Operator-level PC
Can also be used as an engineer station. Engineer standing during system uptime
Intervals can be closed without a permanent connection to the system.
Freelance 800F Process Control Stage
At the process control level, the Freelance 800F system can be controlled by
It consists of a number of process control stations connected to I/O units. you can choose this
Some process stations are in redundant mode (CPU redundancy, fieldbus module redundancy
redundant) or non-redundant mode. Modular pluggable input/output modules
Blocks are freely selected and used according to the type and number of system process signals.
