Carotenoids and Chlorophylls
The chlorophylls and their degradation products 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, lycopene, mutatoxanthin, myxoxanthophyll and 4-keto-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 the concentration, purity 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.

Terms of delivery: Prices are exclusive of shipping costs. Please note that shipments on dry ice are more expensive than standard shipping (EUR 248 to EU countries; EUR 365 to the US mainland, Japan, and South Korea via courier companies. For other destinations, please enquire a shipping price).
