Shipping temperature: ambient

Storage temperature:
- Short term stability: 2-8^oC,
- Long term stability: see individual component labels

Assay format: auto-analyser

Detection method: absorbance - 340

Signal response: increase

Linear range: up to 80 μg/mL of L-malic acid in final reaction solution

Reaction time: ~ 3 min

Detection limit: 20 mg/l

Stability: > 2 years under recommended storage conditions

Method recognition: methods based on this principle have been accepted by AOAC, EEC, EN, NF, NEN, DIN, GOST, OIV, IFU, AIJN and MEBAK

On calibration, the prepared reagent is linear to > 80 micrograms of L-malic acid per ml of assay solution.

• PVP incorporated to prevent tannin inhibition
