Enhanced Sensitivity for Trace Analysis
The ELSD-LTII utilizes a high-efficiency LED and enhanced digital signal/
treatment to minimize noise and deliver optimum sensitivity for trace analysis.
An innovative cell design also reduces band broadening and allows sensitivity
levels below 200 picograms. The high-performance optical detection system
can also be used for combinatorial chemistry and high-throughput screening
applications. The new Low Temperature Evaporative Light Scattering Detector
(ELSD-LTII) is an easy-to-operate, universal detector that identifies analytes with
uniform sensitivity regardless of their spectroscopic properties. It is not a
spectroscopic detector. Instead, it removes the mobile phase through evaporation
and then makes a light scattering measurement of the dried analyte particles.
Features
The ELSD-LTII is ideally suited for such applications as drug discovery, natural products development, combinatorial chemistry, and food and beverage. It will enable you to see all sample components, even semi-volatile compounds, down to the high picogram level.
The ELSD-LTII provides excellent performance during gradients for optimized separations and reduced run times. A unique cell design reduces band broadening to a level similar to UV-Vis detectors while its single mode, low-temperature operation (user defined from ambient 80°C) optimizes sensitivity for those analytes that are easily missed at higher evaporation temperatures typical of competing detectors.
Specifications
| A Universal Detector | Detects all semi- and non-volatile analytes in your sample, including those transparent to other detectors. |
|---|---|
| Fully Gradient Compatible | Handles any combination of volatile mobile phases and gradients for powerful separations and minimized run times. |
| Higher Sensitivity than RI and other ELSDs on the market | The ELSD-LTII is 10 — 100X more sensitive than RI detectors for all samples and under all mobile phase conditions. |
| Detects all analytes, including semi-volatiles, at near-ambient evaporation temperatures | Absolute temperature range (Ambient — 80°C) Commonly used working range (Ambient — 40°C) Semi-volatile analytes and compounds that thermally decompose are easily missed with competing detectors. |
| Accepts a wide range of mobile phase flows | The ELSD-LTII displays excellent signal/noise characteristics over solvent flows from 100µL/min. to 4.0 mL/min. |
| Single-Mode operation | Low temperature operation without accessories, separate operating modes. Most analyses are done using a common set of conditions (Gain 5; Temp 40°C; P 350kPa). |
| Time program air/nitrogen shutoff | A time program method may be used to shut off the inlet gas, ending the problem of wasted gas after work is done. |
| Unique nebulizer/drift tube design offers protection from «fouling» | The nebulizer and drift tube are separated by a glass chamber which protects the evaporation and detection stages from particle buildup. In competing detectors, such buildup contributes to background noise that cannot be solved without maintenance. |
| Stack other detectors on top of the ELSD-LTII | The ELSD-LTII fits perfectly into the modular design of Shimadzu Prominence HPLC hardware. Dimensions: W250 x H450 x D550mm |
