Analytic Instrument QFID-100HR

Analytic Instrument QFID-100HR
Order No.: C01-0147

Short description:

The QFID-100HR measures automatically samples of all kinds. He includes both, a headspace- sampler and a gas chromatograph. Fast, reliable and with a very high precision the headspace-samples will be analyzed. The instrument can separate 18 most important solvents (the analyses of different solvents is possible). A complete analyse of a 20ml HSS-vial needs approx. 8 minutes. The result will be printed out in mg/m², for example.

The instrument is easy to handle because of the auto sampler. The operation does not make it necessary anymore to have qualified personnel.

 

The analyse consists of 3 steps:

  1. Cut out a defined quantity of the sample
    (e.g. 50 cm²), give it into the HSS vial of 20 ml and lock it
  2. Put it into the heating block
  3. Announce the sample at the PC --- Ready!

 

 

System description:

The QFID-100HR integrates a headspace-sampler and an EPC gas chromatograph. The headspace-sampler works automatically in the system, which aims at a high reproducibility. This system is precise pressure controlled. The EPC gas chromatograph increases the carrier gas pressure dependent of the retention time. A special chromatographic column separates all solvents in a special analyse-oven. The oven can be controlled heated between room temperature and 200 °C. Only by controlling pressure and temperature a stabile retention time is possible. The sample, which is separated into the different solvents, gets after the oven to the Flame Ionisation Detector (FID). The FID amplifier sends analogue signals to the PC, where you can see the result.

 

Analytically, the following standard components
are 
determinded:
 (Change/ addition is always possible.)

  • Petrol
  • IPAC
  • MEK
  • 2-Propanol
  • n-Propyl acetate
  • Toluene
  • Butyl AC
  • Ethoxy propanol

 

 
  • Acetone
  • Ethyl acetate
  • Methanol
  • Ethanol
  • MIBK
  • n-Propanol
  • 1-Methoxy-2-propanol
  • 3-Methoxy-1-butanol
 
  • i-Butanol
  • n-Butanol
  • i1-Methoxy-propyl-acetate-2
  • Ethylene-glycol-acetate
  • Butyl glycol
  • n-Butanol

Those are the most important components. Analyses of other different components are possible, but is here not further described.

 

The QFID-100HR consists of the following elements:

(subject to technical modifications)

  • Operation with only one push of a button
  • All regulators are behind a transparent closed cover (work requires no specialists)
  • FID- detector with own temperature control
  • Heating system for the HSS sample vials, up to 200C for 16 different samples
  • An automatically gas sampling valve with heated transfer line
  • Easy interchangeable sample loop
  • Column with pressure-programming at carrier gas
  • Microprocessor for all time controlling with display and keyboard
