    7697A Headspace Sampler
    "Agilent 7697A Headspace Sampler has got great capacity of 111 samples by three 36 vial racks plus three priority positions. Headspace sampler can equilibrate (heat and shake) 12 samples simultaneously. It reduces significantly the time of analysis. The simple robotic arm, which transports headspace vials into the oven and back makes mistakes (headspace vial can fall out) very rarely: the probability is less than 1 ‰. It is for us acceptable. You have to reckon, that this headspace sampler should be connected to the gas chromatograph from the right side. The headspace sampler has got excellent reproducibility. I recommend this product. "

    Agilent 7890B Gas Chromatograph
    "We have bought a new Agilent Technologies 7890B GC System with an Agilent Technologies 7693 Autosampler and OpenLab software. We are satisfied with the parameters of the GC. There is only one disadvantage (comparing with an old 6890 GC): 7890B has got two speed ventilator for the fast oven cooling: the higher speed of the ventilator is very noisy. Luckily we have bought another OpenLab licence for the Data analysis only. So we can evaluate the chromatograms in the quiet office contrary to the noisy laboratory. On the other hand the analysis using 7890B GC is faster than with 6890 GC. The priority in our laboratory is high throughput, which is great. I recommend this GC machine."
