Agilent ESI TOF Biopoly. Anlys Ref. Mass Std Kit G1969-85003

Agilent G1969-85003 is an LC/MS reference mass standard kit intended for ESI‑TOF biopolymer analysis. The kit supplies preformulated calibrants in seven individually sealed ampoules (used for mass calibration, tuning and internal reference) to support accurate biopolymer mass measurements.

Key Features:

• Catalog number: G1969-85003; Technique: LC & LC/MS (ESI‑TOF biopolymer analysis).
• Kit contents: seven ampoules (1 each) — 1.0 M ammonium formate (in nanopure water), 5 mM purine (in acetonitrile), 0.5 mM HP‑0285, 0.1 mM HP‑0321, 0.2 mM HP‑1221, 0.2 mM HP‑1821, 0.5 mM HP‑2421.
• Format and volume: 7 × 2.2 mL sealed ampoules (pre‑measured).

Advantages:

• Provides ready‑to‑use, manufacturer‑formulated reference masses for reliable mass calibration and tuning of ESI‑TOF instruments, improving mass accuracy in biopolymer workflows.
• Includes multiple phosphazine/triazine calibrants and purine plus ammonium formate to cover a broad mass range relevant to biopolymer analyses.
• Pre‑measured sealed ampoules reduce preparation time and lower contamination risk compared with in‑lab dilution of individual calibrants.
