Total digital control of sensitivity, wavelength and signal acquisition. Easy to master software and laptop portability puts the instrument where you need it most!
 |
Enhanced excitation and high efficiency optical design delivers outstanding sensitivity. New integrated computer controls simplify acquisition. Unique modular design brings the user interchangeable accessories as well as scanning capability for HPLC or scanning spectrofluorometer applications. Excitation and emission wavelength reproducibility is excellent, thanks to the digital stepping drive. Across the board, the FL-750 delivers accurate, precise and efficient measurements. This is your most practical choice for a compact fluorescence
detector. The secret of the FL-750, and the key to optimization of detection, lies in the selection of the best excitation sources and dual or single monochromator detection modes. The FL-750 fluorescence detector can always contain two monochromators. The analyzer or emission monochromator can be bypassed when the High Sensitivity Filter Accessory (HSA) is used. This is the most sensitive method to detect emission. Configure your optimized FL-750 detector here. |

Sensitive Fluorescence Detection of static and dynamic flow HPLC samples
- Proven optical design by McPherson, Inc. owned and operated by the same individuals as Schoeffel Instruments, manufacturers of the successful FS770 and 970 instruments.
- Easy to set up and use. Simple installation with internet enabled factory set-up and verification.
- Full computer power for digital control and signal acquisition.
- Use the provided Laptop computer or any PC that accepts PCMIA expansion cards. Set wavelength and scan parameters, timing, detector gain, and send or receive external triggers. Save data directly to your laboratory data system.
- Quality Assurance with Verification of your analytical results, software selectable feature guides you through procedures that verify wavelength calibration and signal-to-noise (H20 Raman measurements.)
- Easy access flow cell for rapid connection and easy exchange, inspection or replacement. All HPLC (micro and preparative) and routine (temperature control, cuvette sequencers, etc.) mount directly to the front of the unit for simple and fast exchanges.
- Dual monochromator design with rapid digitally controlled scanning. For some applications the McPherson filter-emission High Sensitivity Accessory may be preferred.
- Reduce downtime with integral lamp timer in software prompts to Verify signal-to-noise or to replace lamps.
