To maximize the uptime of your GS6000 Headspace analyzer, please note the following:
If new analysis cycles continue to be initiated or the test duration is too long, a vacuum
will be created within the package which will eventually begin to draw product out of the
package or ambient air through the septum – in either case the test has been
compromised.
Always use a full septum, not a portion or piece of a septum and do not penetrate a septum
more than once.
Replace the filter regularly! Passing product through the filter may cause damage to the
analyzer which will not be covered under warranty.
5.6 Additional Test Methods
5.6.1 Direct Injection (syringe)
In some cases, the user may elect to collect a sample(s) using a syringe and inject that sample into the
analyzer. This can be accomplished using the Direct Injection Option (P/N: 898 011) which includes
the syringe (30ml) and the syringe valve.
To prepare the syringe, first connect the filter, valve, and needle to the syringe as shown below.
Prepare the package as mentioned above in section 5.5. Collect the sample by opening the syringe
valve and pulling back on the plunger after you have inserted the needle into the package. Close the
valve prior to withdrawing the needle to capture the sample within the syringe and to prevent
contamination.
1. Assemble the syringe as shown below. Note the valve is closed when the black button is
against the valve body, and open when the white button is against the valve body.
2. Collect the sample as instructed above.
3. Before you can measure the sample, first remove the needle from the end of the syringe valve.
Next, connect the syringe to the sample port (as shown below). Open the valve so the sample
may be extracted from the syringe. At this point, you can calculate your test time by noting the
amount of sample within the syringe and using the calculation mentioned in section 5.4.1.
