Agilent delaytime calib sol for 1260LC/MS 2 x5mL 5190-6887

Agilent part number 5190-6887 is a manufacturer-supplied delay-time (dead-time) calibration solution packaged as two 5 mL vials (2 x 5 mL) intended for Agilent 1260 LC/MS systems and 1260 Infinity fraction collectors. The ready-to-use calibrant contains a UV/MSD-visible marker (thionin acetate) formulated to produce defined chromatographic and mass‑spectrometric signals that are used to determine detector-to-fraction‑collector delay times and calculate delay volumes. It is used during instrument setup, delay evaluation and fraction-collector checkout to ensure correct timing and alignment of UV and MSD signals for accurate fraction collection.

Key Features:

• Manufacturer part number: 5190-6887 (Prep LC Standard #2 / Delay time calibration solution)
• Packaging/Quantity: 2 × 5 mL vials (10 mL total)
• Intended system: Agilent 1260 LC/MS and 1260 Infinity fraction collectors
• Active marker/dye: thionin acetate (UV/MSD-visible calibrant)
• MSD target masses used for evaluation: positive M+H 228.1 and negative M-H 226.1

Advantages:

• Provides a defined UV and MSD marker signal for accurate detector-to‑collector delay time and delay‑volume calibration.
• Ready-to-use, manufacturer-formulated solution reduces setup time and variability in delay calibration procedures.
• Improves fraction-collection timing and reproducibility by ensuring MSD and UV peaks are correctly aligned with the fraction collector.
• Directly supported in Agilent delay-calibration workflows (Lab Advisor/ChemStation and fraction-collector procedures).
