Phytoplankton Pigment Standards

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 chloro pigments are dissolved in 90% acetone and most of the carotenoids are in 100% ethanol except aphanizophyll, astaxanthin, capsaxanthin, α-carotene, α-cryptoxanthin, bacteriochlorophyll a, β-carotene, β-cryptoxanthin, dinoxanthin, lycopene, mutatoxanthin and myxoxanthophyll, which are all in 100% acetone. 

The pigment standards are supplied in sealed vials of 2.5 ml and contain a nitrogen atmosphere. 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 in dry ice.

The concentration most often ranges between 0.4 and 1.7 mg/L (the specific concentration is given on the Certificate-of-Analysis). 

Furthermore, a chlorophyll a standard with a higher concentration (approx. 4 mg/L) is also available.
