3.1.1 Flow-through-needle injector The sample manager's FTN mechanism aspirates a sample and holds it in the sample needle, prepared to inject the sample onto the column. The needle serves as part of the injection flow path when the sample is pushed onto the column. The FTN mechanism facilitates the transfer of LC methods, improves injection accuracy, decreases cycle time for small-volume injections, and does not require learning new injection modes.
In addition to the core modules, the system includes a detector (TUV). 3.2.1 Detector features The detector operates as an integral part of a Waters chromatography system. The Alliance iS TUV Detector is an optical, two-channel, ultraviolet/visible (UV/Vis) absorbance detector designed for HPLC applications. For the Alliance iS System, this detector is configured with Empower Chromatography Data Systems (CDS) software.

The behavior of the filter depends on the filter time constant you select. You can program a filter time to be Fast, Slow, Normal, or Other. If you select Fast, Slow, or Normal, you do not need to specify a value. The filter constant is determined by the sampling rate. If you select Other, you can specify a value but it will be rounded up or down to a value based on the sampling rate.
Page 34
Figure 3–3: Filter time constant comparison 3.2.1.2 Wavelength verification and test The detector’s deuterium arc lamp and integral erbium filter exhibit peaks in the transmission spectrum at known wavelengths. Upon startup, the detector verifies calibration by comparing the locations of these peaks with expected wavelengths based on calibration data stored in the detector’s memory.
• 379.0 nm • 521.5 nm The verification tests for the detector require five minutes of lamp warmup time. If you run the detector continuously, Waters recommends that you perform wavelength verification weekly by cycling power to the detector. 3.2.1.3 Operational modes Detector capabilities include two primary modes of operation.

The default operating function for Dual-Wavelength mode is Absorbance.
and plots the resulting ratio on a data system over one output channel (channel A). Use this function when detecting hidden components within individual peaks. The RatioPlot of a spectrally homogeneous peak appears as a rectangular wave. The RatioPlot of an impure peak appears as a distorted wave. To obtain a RatioPlot, you must operate the detector in Dual-Wavelength mode.
3.2.1.5 Cuvette operations The detector's cuvette option is used to measure the absorbance spectrum of a sample in a cuvette. Note: This section pertains only to use of the optional cuvette cell. The detector's cuvette option is used to measure the absorbance spectrum of a sample in a cuvette.
3.2.2.1 Pressure flow envelope The QSM provides steady (pulse-free) solvent flow at analytical flow rates of up to 5 mL/min at 10,000 psi and linear change to 4000 psi at 10 mL/min. 3.2.2.2 Pressure transducer overview The APT, which measures the pressure on the low-pressure side of the degasser system, is unaffected by altitude or barometric changes.

Figure 4–8: System console 4.6 Priming the system After powering-on the system, you must prime it before the system is ready for use. Requirement: You must prime the system after starting it, as well as after changing the mobile phase, after changing the sample needle, and after the system is idle for four hours or more. Recommendation: If you are introducing new solvents, prime them at 4 mL/min for seven minutes.
sample temperatures, and needle characterization for your next system startup. For details, see the touchscreen. 4.6.1 Priming the seal-wash system Priming the seal wash system is part of the system startup workflow on the touchscreen. Prime the seal wash in the Alliance iS QSM to fill the tubing paths with solvent. Tip: When primed, the seal-wash system is used to lubricate the plungers and flush away solvent and any precipitated salts that were dragged past the plunger seals from the high-...
• Use seal wash that is fully soluble with all chromatographic solvents and that contains at least 10% organic solvent. This concentration prevents microbial growth and ensures that the seal wash can solubilize the mobile phase. • Before priming the seal-wash system, ensure that the volume of seal wash is adequate for priming.
4.6.2 Priming the pump After powering-on the system, prime the pump. Priming prepares a new system for use and for a change in reservoirs or solvents. It also prepares a system for restarting after it is idle for more than four hours. During priming, the vent valve moves to the vent position, allowing flow without disturbing the column or sample manager with minimum back pressure, and directing flow to waste.
Figure 4–9: Location of solvent vent tubing Solvent vent tubing 3. On the touchscreen, tap Setup > Startup > NEXT. 4. From the Prime Solvents screen, select solvent line A, B, C, or D. 5. In the Priming Duration box, specify the number of minutes. Default: 2.0 minutes Recommendation:...
• Preparing a new sample manager for operation. • Preparing a sample manager for operation after it has been idle for more than 24 hours. • Changing the wash solvent. • Removing bubbles from the lines. Ensure that the wash solvent is correctly composed, that it is of LC-MS grade, and that it is miscible with other solvents used in the system.
Table 4–2: The following extension loops are available to use in the sample manager Loop size 50 µL 100 µL - Standard 250 µL 1000 µL 2000 µL Recommendations: • The recommended maximum injection volume is 75% of the total volume of needle and sample loop.
4.8.1 Installing an extension loop in a single-valve system In a single-valve system, the extension loop is installed between the pressure transducer and the sample needle. 1.

• The Automatic setting causes the Sample Manager to wait for three times the volume of the needle and loop combined to flow before the injection valve position is changed to Load, to ensure that the sample has flowed completely out of the needle and loop. •...
Tip: A programmed gradient typically flows through all parts of the instrument that contact the sample. If you initiate the needle and extension-loop offline option before the gradient reaches its final conditions, the highly organic portion of the gradient does not pass through the needle. As a result, the gradient can fail to remove all sample from the needle, resulting in low sample recovery and an increased risk of carryover.
Extra-column effects can also be modified. See the Dwell Volume and Extra-Column Volume: What Are They and How Do They Impact Method Transfer white paper ( 720005723EN) on www.waters.com. Intelligent Method Translator (iMTA) (Page 53).

Note: There can be up to four mobile phase solvent lines, identified by the system as A, B, C, and D. Pay particular attention to how the solvents are lettered in the project because their identifiers determine which solvent line to connect to each bottle. The seal wash, needle wash, and purge solvents have dedicated lines but it is possible for a method to specify filling a bottle with the same preparation as a mobile phase bottle.

You can measure carryover by observing analyte peaks that appear when you run a blank sample immediately after an analytical sample. Waters specifies sample carryover on the Alliance iS System at 0.002% maximum. A common cause of carryover is inadequate washing of the system. Choosing an appropriate wash solvent can minimize carryover for a particular analysis.
