- Description
- Parameters
The LED20G detectors, with UV-VIS Light-Emitting Diodes (LEDs) as the light source, are standalone UV-VIS detectors for preparative and flash liquid chromatography, featuring an internal cell. The LED20G detectors use unique ECOM patented technology that significantly improves the performance of these LED detectors. The parameters are as follows:
| Linearity | R² ≥ 0.999 up to 3.5 AU |
|---|---|
| Typical spectral half-width | 4 nm |
| Noise level at test cell (254 nm, TC 0.75 s) | ±10 × 10-6 AU |
| Drift at test cell (254 nm after 1 h) | 1 × 10-3 AU/hr |
Why the ECOM LED20G series detectors have the best parameters on the market among LED detectors
To explain the difference, the LEDs themselves typically have a peak wavelength tolerance of ± 5 nm and a spectral half-width of 10–20 nm. This is unacceptable for some applications, as e.g. FPLC, and it also causes nonlinearity. However, ECOM‘s solution allows narrowing the spectral bandwidth and selecting the exact wavelength from the LED-diode spectrum.
Key features and benefits of LED20G detectors:
• Sharp, high, and symmetrical spectral peaks thanks to ECOM-patented technology
• Excellent linearity
The pump works as an isocratic pump and, together with ECB2004B, ECB2004BP (ECB2007, ECB2007PC) Gradient Box with Degasser (without Degasser), also as a gradient pump.
ECB2004B, ECB2004BP (ECB2007, ECB2007PC) Gradient Box with Degasser (without Degasser) is equipped with a four-way gradient mixing valve and must be ordered together with the pump.
With a flow rate of 0.001-10.00 ml/min and a pressure limit of 40 MPa, is this pump suited for analytical applications in liquid chromatography. The pump is designed with 2 pump heads - main and auxiliary- connected in series, with a piston diameter of 1/8”.
The new sophisticated unit allows achieving a precise low-pressure gradient, i.e., gradual changes of solvent composition by mixing up to four liquids at the pump’s entry. It is also possible to predefine the percentage of composition when using the pump in isocratic mode. The gradient profile can be defined from a computer or manually using the display and keypad.
There are many improvements which make this pump more reliable, safe and precise. Also, the maintenance is now much easier - e.g., piston exchange is easier because of new construction; a new learning algorithm for pulsation suppression; a leakage sensor, etc.
When necessary, it is possible to use backwashing of pistons (e.g. when using buffered mobile phase).
Also available in configurations made of certified bio-inert materials.
The pump is supported by ECOMAC and Clarity software.
This pump is equipped with the Pressure Compensation Learning algorithm. Thanks to this smart adaptive process, the pump regulates the rotation speed of the camshaft and measures its impact on pressure pulsation to minimize the output pulsation as much as possible. The algorithm, due to its adaptive capacity, is applicable for many combinations of pump working conditions (solvents, columns, etc.).
Key features and benefits of this system:
• Sharp, high, and symmetrical spectral peaks thanks to ECOM-patented technology
• Excellent linearity
• Excellent price-performance ratio
• Compact device dimensions
• Low cell heating due to the LED´s low power supply (0.7 W), which allows use for peptide analysis or FPLC
• Higher sampling speed
• Sophisticated diagnostic software
• Available diodes with wavelengths of 254, 260, 280, and 320 nm; other wavelengths on request
