Gas Chromatograph

Perikin Elmer, Clarus 500

This gas chromatograph is equipped with two detectors via two different injections sites. The detectors are an electron capture detector (ECD) and a flame injection detector (FID). There is a split less injection, and thus two injection sites. In the oven there are two capillary colons. Both are Elite plot Q colons. The GC is also equipped with a Turbo matrix headspace sampler for 110 samples. Analyses typically run are detection of carbon dioxide, methane, ethylene, propane and nitrous oxide.

TOC analyzer

Formacs HT-I TOC/TN, Skalar

This carbon analyzer compose of an analytical compartment with an auto sampler with a capacity of 80 liquid samples, and a solid material combustion oven. Liquid samples for organic carbon are injected into a furnace with a temperature of >800°C, and the gas then passes a non-dispersive infrared detector (NDIR-detector). Solid samples can be combusted in a separate oven (up to 1100°C). Samples are then manually fed using crucibles into the oven. The gas is analyzed on the NDIR-detector on the analyzer. There is also a separate injection site for analysis of inorganic carbon in liquid samples. Total nitrogen in water can also be measured at the same time as organic carbon. The TN is detected with a ND25-detector (chemiluminescent detector). 

Nutrient analyzer

QuAAtro, Seal Analytical

A segmented flow analyzer equipped with an autosampler for 180 analyses. It is also equipped with an automatic on-line digestion of samples for total-element analyses. The analyzer is equipped for analyses for low concentrations of PO4-P, NO2+NO3-N, NH4-N, TN and TP and also for Cl.

Fluorometer

Perkin Elmer, LS-55

The appliance is equipped with a 1cm cell holder and a 96-well plate reader that can be fixed to the analyzer for automatic detection of samples. There is also an accessory for solid samples detection.

Liquid scintillation counter

Beckman, LS-6500

The appliance has been set up for counting of 3H and 14C, but more isotopes are available. Results output can both be printed or saved as a file on a computer.

Respicond

One 96-unit Respicond instruments

The Respicond measures the evolution of CO2 in soils, sediments or other matrices in incubation chambers with a very high accuracy and time resolution. The temperature in the chambers is regulated in insulated water-baths that allows for incubation studies at different temperature.

Flow Cytometer

BD, FACSVerse

With this instrument it is possible to measure and count particles smaller than 50 µm. It is equipped with a red and a blue laser (4 colors). It has a manual port as well as a sample rack with up to 40 samples. Typical applications has been counting of bacteria and phytoplankton.

Microbalance

Mettler Toledo XPR 6UD5

A microbalance with the capacity to weigh samples up to 6.1 g, a readability of 0.0005 mg and a minimum weight of 0.06 mg. It is equipped with an antistatic unit.
