Carotenoids and Chlorophylls
- Pigment standards derived primarily from phytoplankton
- Ready-to-use HPLC grade standards with the concentrations provided
- Especially applicable in calibration of instruments, e.g., HPLC
- Shipped in dry ice all over the world
- Certificate-of-Analysis shows the concentration and the HPLC chromatogram
The chloropigments are dissolved in 90% acetone and most of the carotenoids are in 100% ethanol except astaxanthin, capsaxanthin, α-carotene, β-carotene, α-cryptoxanthin, β-cryptoxanthin, dinoxanthin, lycopene, mutatoxanthin and myxoxanthophyll, which are all in 100% acetone. The standards are flushed with 100% N2 and supplied in sealed vials with 2.5 mL. The pigment standards are shipped in dry ice. When stored frozen (below -20 °C), the pigments are stable for at least three years. The standards should, however, be used immediately after breaking the seal. Certificates-of-Analysis specifying concentrations, stability, storage and handling accompany the standards when shipped.
The concentration most often ranges between 0.6 and 1.5 mg/L (the specific concentration is given on the Certificate-of-Analysis). Furthermore, a chlorophyll a standard with an higher concentration (approx. 4 mg/L) is also available.
