    ACQUITY UPLC I-Class Series System Waters designed the ACQUITY UPLC I-Class Series system for optimum performance when running difficult assays. Configure it with a mass spectrometer to take full advantage of the system’s design enhancements. 1.1 UPLC technology In 2004, Waters made significant advances in instrumentation and column design to introduce UPLC technology to the field of separation science.
  • Page 14 Figure 1–1: Evolution of particle size in liquid chromatography and the impact on separation efficiency It is apparent from the figure, above, that using 1.7-µm particles achieves higher efficiency that persists as flow rate increases (lower HETP indicates higher efficiency). When operating in this area of the plot, the peak capacity and the speed of a separation can set limits well beyond those of conventional HPLC technology.

  • Page 15: Features Of The Acquity Uplc I-Class Series System

    1.2 Features of the ACQUITY UPLC I-Class Series system The ACQUITY UPLC I-Class Series system significantly improves the results of traditionally challenging separations. When compared to systems typically used for difficult assays, the I-Class Series system offers these advantages: •...

  • Page 16: Binary Solvent Manager

    1.3 Binary solvent manager The ACQUITY UPLC I-Class Series system employs a binary solvent manager that, like the system, is optimized for sub-2-μm particle liquid chromatography and uses reduced fluid volumes. New pressure management capabilities extend the flow rate envelope for the system to support ballistic gradients.

  • Page 17: Mass Spectrometry

    1.6 Mass spectrometry When you configure an ACQUITY UPLC I-Class Series system with a mass spectrometer, the system’s design enhancements enable you to separate more peaks with better peak shapes to aid quantitation. You also benefit from improvements in sensitivity and flexibility.

  • Page 18: Binary Solvent Manager (Bsm)

    Sample manager Binary solvent manager The ACQUITY UPLC I-Class Series core system includes a binary solvent manager, a sample manager - flow through needle or sample manager - fixed loop (SM-FTN or SM-FL), a column heater (CH-A), detectors (tunable ultraviolet, photodiode array, eλ photodiode array, or mass spectrometry), and an ACQUITY UPLC column.

  • Page 19: Sample Manager-Fl (Sm-Fl)

    See also: ACQUITY UPLC Sample Manager - Fixed Loop PLUS Overview and Maintenance Guide on your documentation media, or at Waters.com, for more information on other injection modes. 1.7.4 Column heater (CH-A) Column temperature variations can shift peak retention times and alter peak shapes, increasing the difficulty of achieving precise results.

  • Page 20: Column Manager (Optional)

    1.7.6 Column manager (optional) The ACQUITY UPLC I-Class Series column manager (CM-A) is an option for helping to ensure precise, reproducible separations. The CM-A can regulate the temperature of columns from 4 °C to 90 °C. Its troughs can accommodate columns of up to 4.6-mm I.D. and up to 150-mm length, depending on the configuration.

    Note: The ACQUITY FlexCart is not supported with the ACQUITY QDa detector or any ACQUITY UPLC I-Class Series system with dual detection (split-stack configurations). 1.7.11 Column technology The ACQUITY UPLC columns are packed with the following: 1.7-µm, bridged, ethylsiloxane, hybrid;...

  • Page 22: Detection

    1.7.11.1 eCord technology ACQUITY UPLC columns include an eCord column chip that tracks the usage history of the column. The eCord column chip interacts with the system software, recording information for as many as 50 sample queues run on the column. In regulated environments, the eCord column chip provides documentation of the column used in the validation method.

  • Page 24: Performance Optimization

    When performing fast UPLC analyses, a peak of interest can be less than 0.5 seconds. Waters recommends a sampling rate of 25 to 50 points across the peak, which provides good quantitation and peak representation.

  • Page 25: Dispersion

    An ACQUITY UPLC I-Class Series system typically exhibits a bandspread (5σ) of ≤ 7µL or ≤ 9µL when configured with an SM-FL or SM-FTN, respectively. An Alliance HPLC system can exhibit a bandspread between 35 µL and 50 µL.

  • Page 26: Carryover

    2.3 Carryover You observe carryover in chromatographic systems when a previously injected analyte appears as a peak in the chromatogram of subsequent samples. Carryover tends to occur when a small amount of analyte remains in the system after a sample is injected. You can measure carryover by observing analyte peaks that appear when you run a blank sample immediately after an analytical sample.

  • Page 27: Cycle Time (Between Injections)

    Leaks at high-pressure fittings (downstream of the i2Valves) can leak solvent but do not introduce air. To prevent leaks, follow Waters’ recommendations for the proper tightening of system fittings. Note specifically that different techniques apply to retightening fittings versus installing them for the first time.
  • Page 28 Requirement: Use eye protection when performing this procedure. Recommendations: • To prevent band spreading, ensure that the tubing is fully bottomed in its connection port before tightening the compression screw. • For easier accessibility, use long compression screws to attach tubes to the injector and vent valve.
  • Page 29 Rotate the compression screw, clockwise, into the connection port until the screw is finger- tight. Using a permanent marker, mark the compression screw at the 12-o’clock position. Mark the connection port at the 9-o’clock position. Ensure that the tubing makes contact with the bottom of the connection port, and use the 1/4-inch open-end wrench to rotate the compression screw clockwise 3/4-turn until the two marks line up.
