VMA, HVA, 5-HIAA Urine Calibration Standard
VMA, HVA, 5-HIAA Urine Calibration Standard, lyophilised
For VMA, HVA, 5-HIAA and 5-HIAA in Urine by HPLC (1000/B, 51000)
This lyophilised calibrator from Chromsystems is based on human urine and should be used according to the instruction manual. It is designed to calibrate the measurement method in clinical diagnostics for the quantitative determination of VMA, HVA, 5-HIAA in urine. While following the instructions the calibrator should be handled and measured in the same manner as a patient specimen.
An alternative is the aqueous calibration standard (order no. 1003/B), which is directly injected into the HPLC system without sample preparation.

| Storage conditions | Stored at +2 to +8 °C unopened calibration standards are stable until the expiry date which is stated on the vial labels. The reconstituted calibration standard should be stored tightly capped at +2 to +8 °C. Generally the calibration standard can be stored for two days at +2 to +8 °C. If the calibration standard cannot be analysed within this period, it should be aliquoted and stored frozen below –18 °C (up to 3 months). |
