Agilent Cobalt (Co) Internal Std 5000 ug/g 200g 5190-8714

The Agilent Cobalt (Co) Internal Std 5000 µg/g (part number 5190-8714) is a single‑element internal standard supplied as cobalt at 5,000 µg/g in a 75 cSt hydrocarbon oil matrix and packaged as 200 g. It is intended for matrix‑matched oil and petrochemical analyses where a stable cobalt internal standard is required for spectrometric methods and oil analysis workflows. The product is used to spike samples or calibrants to monitor instrument stability, correct for matrix effects, and support organometallic/petrochemical testing.

Key Features:

• Concentration: 5,000 µg/g (5 mg/g) cobalt (Co).
• Matrix/solvent: 75 cSt hydrocarbon (mineral) oil.
• Package size / quantity: 200 g.
• Intended application domain: oil analysis / petrochemical / organometallics (internal standard use).

Advantages:

• Matrix‑matched formulation (75 cSt hydrocarbon oil) reduces matrix effects when spiking hydrocarbon/petrochemical samples, improving accuracy in oil analyses.
• High single‑element concentration (5,000 µg/g) provides a robust, easily detectable internal standard signal for routine instrument monitoring and drift correction.
• 200 g bulk packaging supplies larger labs or frequent users, lowering the need for frequent reordering and reducing run‑to‑run variability from multiple smaller bottles.
