1.3.7 FlexCart (optional)

The optional FlexCart provides a mobile platform for the system. It can hold the system
instruments, as well as the PC and monitor, and it provides electrical outlets for system
instruments and integrated waste management. Used with a mass spectrometer, the cart's
adjustable height lets you position the column outlet close to the inlet probe, minimizing system
dead volume.
Note:
The ACQUITY FlexCart is not supported with the ACQUITY QDa detector or any
ACQUITY UPLC H-Class Series system with dual detection (split-stack configurations).

1.3.8 Post-Injection Volume Kit (optional)

This optional kit includes a 50-µL extension loop that provides additional post-injection mixing.
This additional volume can address peak distortion caused by injections of high organic sample
diluents.
For more information on installing this extension loop, see

1.3.9 Detection

The detectors compatible with your system detect and quantify concentrations of sample analyte.
The system accommodates these detectors:
• Photodiode array (PDA)
• Photodiode array eλ (PDA eλ)
• Photodiode array with TaperSlit (PDA-TS)
• Tunable ultraviolet (TUV)
• Evaporative light scattering (ELS)
• Fluorescence (FLR)
• Refractive index (RI)
• ACQUITY QDa
• Conductivity detector (2432)

1.3.10 Column technology

The ACQUITY UPLC columns are packed with the following: 1.7-µm, bridged, ethylsiloxane,
hybrid; 1.8-µm, high-strength silica particles, or 1.6-µm solid-core particles that can mechanically
endure high-pressure conditions. The column hardware and the matched outlet tubing can
withstand as much as 103,421 kPa (1034 bar, 15,000 psi). The column dimensions allow optimal
