Facilities

 Our lab is well equiped with several instruments for various uses, from biomass conversion to catalyst characterization. Below is a summary of our equipment and the person of contact.

 

 

Agilent Infinity 1260 HPLC

There are 2 HPLC systems in our lab running independently of each other and both equipped with a DAD for UV-Vis spectrophotometry and a RID for RI measurements. The first system is fitted with a Bio-Rad Aminex HPX-87H column running with acidic mobile phase for the analysis of sugars and organic acids from biomass.

 

The second system is fitted with a Bio-Rad Aminex HPX-87P column running with neutral mobile phase for the analysis of sugars from biomass. The HPLC cluster is also equipped with an analytical fraction collector which can be switched between either systems.

Flow reactors

We currently have 2 continuous flow reactors set up with a max temperature of 900 degrees celsius. They are connected with a variety of inlet gases as well as with a pump for liquid reactions. These reactors can be connected to a GC for online gas product analysis and are fitted with a 200 mL liquid collecting tube. Uses include kinetic studies on catalysts as well as biomass reactions.
