4600 Optical Atomic Absorption Spectrometer

4600 Optical Atomic Absorption Spectrometer

I.Features

1. Flame, graphite furnace and  , graphite furnace and  power machine integration, no mechanical switch and is able to achieve flame and graphite furnace atomic determination.

2. New engineering plastics, smooth-shaped cavity spray chamber.

3. 8 lighthouse automatically switch , can use 8 lights to preheated at the same time , one can be accessed by a high-performance elements light.

4. Automatic lighthouse regulating device (utility patent).

5. Graphite furnace autosampler sample position up to 100.

Flame System

1. Digital setting controls acetylene flow is more accurate, more convenient to operate

2. Safe operation of the entire system, regardless of power cut off, flame abnormal, pressure is low or the head does not match, the flame safety system will alarm and automatically shut off the gas, to prevent tempering, ensure the user and equipment from injury and damage.

Graphite furnace system:

3. When tomb furnace cut off  water, cut off gas, overheating,it alarm automatically
