We are a group of scientists and engineers who use carbon dioxide parameters (DIC, TAlk, and pCO₂) as measures of biological activities such as biological production and respiration in aquatic environments. We provide you with high quality instruments at affordable prices. We are ready to use our experiences to help address your scientific issues. With these goals in mind, Apollo SciTech was setup in 2001. Since then we have built Dissolved Inorganic Carbon (DIC) Analyzer (model AS-C1, AS-C2, and now AS-C3), Seawater Total Alkalinity Gran Titration System (model AS-ALK1 and now AS-ALK2), and Underway pCO₂ Monitoring System (model AS-P2) for users around the world including the U.S., Canada, Australia, Ukraine, France, the mainland China, Taiwan, and Hong Kong. A unique feature of our DIC analyzer and TALK titrator is the small sample volume.
