n Shimadzu TOC-L Series Total Organic Carbon Analyzer
The Shimadzu TOC-L Series Total Organic Carbon
Analyzer can be used to conduct the following types of
measurements.
• Measurement of total carbon and nitrogen content in
water, quantity dissolved, quantity suspended*
• Measurement of total carbon, organic carbon,
inorganic carbon in water
• Measurement of dissolved CO2 in water
Thus, the TOC-L series can be utilized for such
applications as the following types of microalgae
research.
• Obtain information related to the physiological state
and the properties of microalgae.
• Understand the changes in cell material with respect
to changes over time in the culture and changes due
to light and dark environment.
• Understand quantitatively the carbon and nitrogen
balance in the culture system.
The TOC-L Series instruments can be used to conduct
measurement using very small volumes of sample in the
range of 10 to 20 mL, making it suitable for laboratory
scale studies.
* The TNM-L Total Nitrogen Unit option is required for nitrogen (TN) Fig. 3 TOC-L Total Organic Carbon Analyzer + TNM-L Total
measurement. In addition, filtering and centrifugal separation, etc. Nitrogen Unit
are required for separate measurement of samples in the dissolved
state and suspended state.
