德国LTB公司 LIMES

仪器简介：
The main components of the LIMES are: 
- the laser system 
(Nitrogen laser MNL 200 and Automated Tuning Module ATM) 
- the spectrometer/detector unit 
- the beam guidance via fibres 
- the customized sample handling 
- the PC with the operation and evaluation software Sophi for LIMES 
All components are incorporated into a compact set-up that is integrated
into a portable under-table casing.

主要特点：
LTB designed Laser Induced Multi Emission Spectrometer , or LIMES, combines the advantages of laser technology and highly sensitive detection electronics in a compact laser fluorescence analyzing system. It allows in comparison with conventional fluorescence lamp excitation:
1) an increase in the sensitivity of up to 3 orders
2) a rise in the measuring velocity
3) a miniaturization of the samples
