MS systems. 2.2 Servicing A periodic maintenance kit is available from Teledyne Isco (part #60-5247-024). The kit contains instructions, parts, and equipment for servicing the ELSD. Contact the factory for more information.
340CF ELSD Section 2 Introduction 2.3.1 Nebulization Nebulization transforms the liquid phase leaving the column into an aerosol cloud of fine droplets. The size and uniformity of the droplets are extremely important in achieving sensitivity and reproducibility. The ELSD uses a special concentric flow nebu- lizer and a constant flow of an inert gas to ensure a narrow droplet size distribution.
340CF ELSD Section 2 Introduction 2.3.2 Evaporation After passing through the nebulization chamber, the aerosol cloud is propelled through the heated evap- oration tube, assisted by the carrier gas. In the e v a p o r a t i o n t u b e , t h e...

340CF ELSD Section 4 Operation When setting the ELSD temperatures for a new method, select 25°C for spray chamber temperature and 55°C for drift tube tem- perature. These temperatures should then be adjusted for the best signal to noise ratio during method optimization. For the...
340CF ELSD Section 4 Operation As the Spray Chamber temperature increases from 0° to 15°C, more of the vapor phase goes to Drift Tube and not to the drain and the signal becomes larger. When the Spray Chamber is heated from 15°C to 25°C the signal decreases because the vapor is partially evaporated in the spray chamber.
340CF ELSD Section 4 Operation Figure 4-3 Drift Tube Temperature Effects The effect of temperature on signal between 45°C and 50°C is small, but as the drift tube temperature increased above 60°C the signal height decreased. A drift tube temperature setting that is too high could vaporize the analyte and cause a loss of sensitivity.

340CF ELSD Section 4 Operation Column Pre-Treatment Chromatographic columns may introduce particles into the mobile phase, which may lead to increased noise and blocked fluid paths. It is recommended that the chromatographic column be flushed with at least 10 column volumes before it is connected to the ELSD.
