Inductively Coupled Plasma Optical Emission Spectrometer ICP-6800
Main Features
Performance stability
The use of all-solid-state rf power supply, with small size, high
efficiency, stable output power, with a variety of protection
functions and many other advantages, the load using fully automatic
matching technology, matching speed, improve the efficiency of the
use of power supply and the stability of the instrument, and make
the whole ignition process simple and convenient.
Injection automation
The instrument is equipped with a four-channel twelve-roller
high-precision peristaltic pump, which can guarantee the precision
of injection and prevent liquid accumulation at the same time. The
speed of the peristaltic pump can be adjusted continuously to meet
various test requirements of customers.
Flow control parameters
Adopt imported high precision mass flow controller.
High precision constant temperature system
The whole optical path of adopt the precision constant temperature
protection system. The temperature control can be set in real time
according to the actual ambient temperature of the customer's
laboratory, without the need to turn on the air conditioner
continuously for a long time. Temperature control precision ≤±0.1%,
precision constant temperature protection system to ensure the
stability of the optical path and makes the test data more stable.
