Instrument:
High-performance liquid chromatography (MR10-04 Leg1 - )
Photosynthetic pigments data by HPLC during MR11-05 Leg2 cruise were obtained by the following methods. See Data List for available data at each station. Water sampling, filtration, and devices and standard materials for analysis for this method are outlined below. For further information, please see Cruise Report.
1) Vertical sampling : Niskin
2) Surface sampling : Bucket
3) Sampling layer: : 3-14
4) Filter and filtration : Whatman GF/F 47mm was used at dark place.
5) Freezing and drying : 0 degC, 6 hours
6) Extract reagent : N,N-dimethylformamide (HPLC-grade)
7) Extract time : -20degC, 24 hours
8) Preservation period of frozen filter paper : a few days
9) Analysis place : MIRAI
10) Analysis device : High-performance liquid chromatography (HPLC)
11) Stationary phase : YMC C8 column, 150Ă—4.6mm, 35degC
12) Mobile phase (unit in volume ratio):
Eluant A: methanol : acetonitrile : aqueous pyridine solution (0.25M pyridine) = 50 : 25 : 25
Eluant B: methanol : acetonitrile : acetone= 20 : 60 : 20
13) Analysis pigment number : 26 pigments (see cruise report)
High-performance liquid chromatography (HPLC) is a kind of column chromatography to separate, identify, and quantify individual chemical compounds from mixtures of compounds by a difference of chemical attractions with the column's stationary phase.
A high pressure to the mobile phase allows for a better resolution and sensitivity than ordinary column chromatography.

In MIRAI, HPLC are used for separating and quantifying various phytoplankton pigments in natural seawater. Taxonomic composition of phytoplankton can be estimated by measuring composition of their pigments. In this cruise, reversed phase C8 Columns and pyridine are used as stationary and mobile phases, respectively, based on a method of Zapata et al. (2000). More pigments can be separated by using C8 column than C18 column which was conventionally used. Pyridine used as a mobile phase is suitable for a better separation of phytoplankton ingredients such as carotenoids and chlorophylls.
