UltiMate 3000 Series: Fluorescence Detectors FLD-3100 and FLD-3400RS 4.6 General Guidelines for Detector Operation The following sections offer general guidelines for detector operation. For information about how to optimize the detector performance, see section 5.7 (→ page 77). 4.6.1 Mobile Phases Mobile phase quality significantly affects detection limits and instrument performance.
UltiMate 3000 Series: Fluorescence Detectors FLD-3100 and FLD-3400RS 4.6.2 Mobile Phase Delivery System The pumping system should deliver continuous flow while ensuring intermixing of the mobile phase (if gradient elution is used). Fluctuations in pump backpressure can cause baseline noise. If the noise is synchronized with the pump stroke, check your HPLC pump. The plastics present in some solvent delivery systems from third-party manufacturers are not fully compatible with the solvents commonly used in chromatography.

UltiMate 3000 Series: Fluorescence Detectors FLD-3100 and FLD-3400RS 5.6 Operational Modes of the Detector 5.6.1 Single-Channel Mode A fluorescence detector is usually operated in single-channel mode, that is, a single excitation/emission wavelength pair is measured. As this mode provides the highest possible data rates and best signal-to-noise ratio, always use the single-channel mode for very small peaks.
UltiMate 3000 Series: Fluorescence Detectors FLD-3100 and FLD-3400RS 5.6.3 Zero Order Mode In Zero Order Mode, the grating of the emission monochromator is set to the position of zero order. In this position, the monochromator lets the entire spectrum pass, rather than only a certain wavelength.
Page 83
UltiMate 3000 Series: Fluorescence Detectors FLD-3100 and FLD-3400RS Emission Scan The wavelength on the excitation monochromator is kept constant, while the emission monochromator scans a wavelength range. The result is an emission spectrum of the sample. Synchro Scan A user-defined excitation wavelength range is scanned, while the emission wavelength is scanned synchronously with a fixed distance.
UltiMate 3000 Series: Fluorescence Detectors FLD-3100 and FLD-3400RS Complete the following steps to record an emission spectrum: 1. Open the Commands dialog box for the detector.

UltiMate 3000 Series: Fluorescence Detectors FLD-3100 and FLD-3400RS 5.7.3 Filter Wheel Setting (FLD-3400RS only) To prevent this stray light from reaching the PMT, additional optical edge filters are installed in the light path between the flow cell and the emission monochromator. This reduces direct scattering of light from the light source.
UltiMate 3000 Series: Fluorescence Detectors FLD-3100 and FLD-3400RS • You can manually select the filter wavelength. Available filters are 280 nm, 370 nm, 435 nm or 530 nm. The selected emission wavelength must not be more than 15 nm below the filter wavelength. In special situations (for example, if the emission wavelength is near the cut-off wavelength of a filter), setting the filter manually may provide better results than the Auto setting.
UltiMate 3000 Series: Fluorescence Detectors FLD-3100 and FLD-3400RS Data collection rate • Data can be generated with a maximum collection rate of 100 Hz or 200 Hz (FLD-3400RS under Chromeleon 7.1 or later). The LongLife lamp mode supports a maximum data collection rate of 20 Hz. •...
UltiMate 3000 Series: Fluorescence Detectors FLD-3100 and FLD-3400RS 5.7.6 Flow Cell Temperature The temperature of a sample influences its fluorescence. Thus, a problem with fluorescence detection is that the results can strongly be influenced by fluctuations in ambient temperature. The FLD allows you to heat the flow cell and thus keep temperatures inside the flow cell at a constant level.
UltiMate 3000 Series: Fluorescence Detectors FLD-3100 and FLD-3400RS You can select the Lamp Mode directly in the Program Wizard (→ page 68) if you have selected a single wavelength channel. Tip: You can change the lamp mode during a measurement, for example, from LongLife mode (between the peaks) to Standard or HighPower mode (for the interesting peaks).
