This system is suited for preparative and flash chromatography by the constant flow rate of mobile phase (0.1-100 ml/min). Sample injecting is provided automatically using three-way valve on the input of the system. The fractions are collected by
means of the six-way valve on the system output. Chromatographic software ECOMAC controls the system and collects data.
Whichever ECOM UV detector can be used in the system (Sapphire, Opal or Flash 06).ALPHA 100 Plus Isocratic Pump:
Flow rate 0.1–100 ml/min and limit of pressure 15 MPa is this pump suited for preparative applications in liquid chromatography. It is designed with two pump heads connected in parallel with the piston diameter of 3/8”.
There are new improvements in piston suspension which has new plastic slide bearing and exchange is now easier. Bypass valve has been improved also and is now easier to operate it.
Intuitive operating using simple keypad allows easy chose functions as follow:
- Flow rate
- Maximal flow rate- PURGE ( for priming and washing)
- Low-pressure limit
- High-pressure limit
- Pulsation compensation on-off
- Pressure unit (PSI, MPa or bar)
- Control mode ( by keypad, RS232 or using voltage)
- Display brightness
Two LED displays allows to watch (also from a distance) adjusted flow rate and operating pressure. By pump function
choosing, give you this displays enough of information for adjusting.
By work with buffered solvents is possible to use pistons backwashing.Flash 06S DAD 600 Detector:
Is a UV diode array detector, which allows measuring the absorbance of four wavelengths simultaneously in one cell just as measuring of whole spectrum (scan). This unit is used in liquid chromatography to verify analyzed samples by means of four wavelengths or in situations when some peaks absorb on different wavelengths. It is possible to use the detector in flash and preparative applications. By using analytical cell can be detector used also for an analytical purpose.
Noise level at 254 nm is ±5·10-5 AU with a test cell. The unit’s DAD (diode array detector) design offers many advantages:
- Absorbance measuring on four wavelengths simultaneously
- Wavelength setting from 200 up to 600 nm in increments of 1nm
- Scan of the whole spectrum is possible in each time
- Lampwork hours are counted using the built-in counter
- The cell is easy to replace from the side of the detector
- Powering by 90-264 V
- Unit is controlled by RS232 interface
