Lang Lab Equipment

We love our instruments. We have state of the art equipment to analyze the concentration and isotope composition of any number of organic compounds.




For the 13C, 15N, and 2H isotope analysis of individual organic compounds, including lipids and amino acids. With offline preparation we can also do the isotope analysis of DOC (dissolved organic carbon), DIC (dissolved inorganic carbon), and organic acids. Consists of a Trace GC 1310 linked to a GC-Isolink II and Delta V Plus


HPLC UltiMate 3000 with UV/VIS and Fluorescence detector 

Our HPLC (high performance liquid chromatography) does any number of jobs. We use it for the concentration analysis of organic molecules such as organic acids, but also the separation of these compounds for off-line compound specific isotope analysis

CEM Discover Hydrolysis System 

For vapor phase hydrolysis. This approach for measuring total hydrolizable amino acids minimizes the potential for contamination. 


SP Scientific Freeze Dry System

With an oil-free scroll vacuum pump to minimize potential contamination


Varian GC with FID and MS

An oldie but goodie. This Varian Chrompack CP-3800 Gas Chromatograph with an FID and a Saturn 2000 MS is used for the identification and quantification of organic molecules such as lipids


Remote Water Sampler 

This 48-port water sampler is built off an AquaMonitor (WS EnviroTech) and can be deployed remotely, taking samples at set times. It has been used to collect >50 L of low temperature hydrothermal fluids from Baby Bare Seamount, IODP hole 1026B, and Axial Seamount.


Our homemade freezer temperature monitors

It may not be the most exciting but we are proud of them regardless. Emma recently used a Rasberry Pi to build temperature monitors for all of the freezers and fridges in the lab. Now, if one goes over a set point, it automatically sends an email alert to the group. Many thanks to Philip Crotwell for the guidance! You can check out the temperatures anytime at:
