S 4245/ S 4250 – the UV/VIS Detectors for routine analyzes in HPLC
The UV/Vis - Detektors S 4245 und S 4250 are variable wavelength UV/Vis detectors for routine analysis and sophisticated research. The dual lamp design offers a wavelength range of 190 – 900 nm with a low baseline noise. The front - accessible flow cell can easily be exchanged, as can be the lamps which are accessible through a side panel in the instrument housing.
Integrated Wavelength Program
The UV/Vis - Detektoren S 4245 und S 4250 features a wavelength program to change the selected wavelength over time. With this feature the optimum wavelength can be selected for each analyzed substance according to its retention time.
Integrated Peak Detector
The integrated Peak Detector works as a basic fraction collector. The peak detection level can be freely programmed for peak start and peak end to enhance the collection purity. An integrated 24V output for switching a solenoid valve is used for the fraction collection, which is automatically operated with a selectable time delay.
Optional - Dual - Wavelength
The UV/Vis - Detektors S 4245 und S 4250 are available with an optional second wavelength. This feature enhances the Wavelength Program feature that you can measure 2 different wavelengths at the same time. A second D/A converter output comes with this option to keep the system flexible to be used with any data acquisition software available.
Optional - ONLINE - SCAN
Another option for the UV/Vis - Detectors S 4245 und S 4250 is the Online Scan. With the Online Scan whole spectrum information can be gathered at a certain time. This scan information is stored internally and can be accessed at any time. The Online Scan is a good alternative to a full UV PDA detector.

ZAM 3000 - ELSD Detector for routine analysis in HPLC
The Evaporative Lightscattering Detector ZAM 3000 is an universal detector for HPLC. It is used to analyze components which do not have UV absorption, cannot be separated with an isocratic solvent and must use a gradient elution, which cannot be used with a refractive index detector. Only mobile phases without any buffers should be used.
In contrast to other evaporative light scattering detectors all parts of the the ZAM 3000 detectors which come in contact with the sample are made of PTFE or glass. By this this parts are inert to common solvents and easy to clean. One more advantage of glass parts is the fact that contammination can be located easily. The nebulization takes place in the glass nebulization chamber. From here the aerosol is guided into the evaporation chamber which is made of glass, too. The solvent evaporated and only small sample particles reach the detection chamber. Here this particles pass a beam of bright light. By this the light is scatterd in all directions. The scattered light is detected by a photomultiplier in an angel of 120°. The signal is amplified and exported as the detector signal. All parts which get in contact with the sample can be un-mounted and cleaned easily.

ZAM 4000 ELSD Detector for routine analysis in HPLC
The Evaporative Light Scattering Detector ZAM 4000 is an universal detector for HPLC. It is used to analyze components which do not have UV absorption, cannot be separated with an isocratic solvent and must use a gradient elution, which cannot be used with a refractive index detector. Only mobile phases without any buffers should be used.
It differs from the ZAM 3000 evaporative light scattering detector in the gas flow regulation of the additive gas. The ZAM 3000 utilizes a mass flow controller which is replaced by a regulation valve in the ZAM 4000 instruments. As the additive gas flow is not changed in most applications this results in a lower price for the ZAM 4000. In contrast to other evaporative light scattering detectors all parts of the the ZAM 4000 detectors which come in contact with the sample are made of PTFE or glass.
