Biosystems Reagent Vanilmindalnaya Acid

Reagents and Standard are stable until the expiry date shown on the label when stored tightly closed and if
contamination is prevented during their use.bts 350 semi automatic analyzer

 

Biosystems Reagent Vanilmindalnaya Acid PRINCIPLE OF THE METHOD

Vanilmandelic acid (VMA) is retained by an anionic exchange resin, being eluted thereafter once the interfering
substances are washed away. The VMA is quantified spectrophotometrically as vanillin after periodate oxidation
under alkaline conditions1,2,3

STORAGE

Store at 2-30┬║C.
Reagents and Standard are stable until the expiry date shown on the label when stored tightly closed and if
contamination is prevented during their use.
Indications of deterioration:
Ôłĺ Reagents: Presence of particulate material, turbidity, absorbance of the reagent blank over 0.050 at 360 nm.
Ôłĺ Microcolumns: Absence of buffer over the resin bed.

AUXILIARY REAGENTS

Ôłĺ Concentrated hydrochloric acid (analytical grade).

REAGENT PREPARATION

Reagents (B) and (C): Dissolve the dry powder in 10 mL of distilled water. Stable for 5 months at 2-8┬║C.
Standard (S): Dissolve the dry powder in 5 mL of Reagent (3) and add one drop of concentrated hydrochloric
acid. Stable for 2 months at 2-8┬║C.

ADDITIONAL EQUIPMENT
Ôłĺ Spectrophotometer or photometer with a 360 nm filter (358-362).
Ôłĺ Thermostatic water bath.

Biosystems Reagent Vanilmindalnaya Acid SAMPLES

Urine. 24 hours specimens collected by standard procedures.
Keep at 2-8┬║C and use within 24 hours. Samples can be stored at 2-8┬║C for a maximum of 5 days or 1 month at
Ôłĺ20┬║C if adjusted to pH 1-2 with concentrated hydrochloric acid (HCl). Centrifuge or filter before testing
