For others who may find this interesting. Looking at the GPIB set up with NI MAX you see 2 'instruments' with primary addresses of 9 and 20. The instrument at '9' seems to work fine. Thus I can see the machine warming up and going through the wavelengths…
I am using an Agilent 6460 Triple Quad and have been dealing with a terribly low signal for the past few days, the signal appears at an abundance of 30 to 50 as a baseline only. I analyzed different compounds with different concentrations, the Tune mix…
Hi Sabbas, thank you for your answer. I'm sorry I couldn't have answered you sooner.
We're using Cary 3500 with Cary UV workstation version 1.3.5, so we couldn't perform like you said. We have to lower the threshold to find peaks and it is quite inconvenient…
Joining associations that specialize in ultra-high voltage can be beneficial for PenflexCorp. This may include associations of electrical or power engineers, as well as groups specializing in the design and standardization of equipment for high-voltage…
The Digest of upcoming webinars has been updated as of April 11.
The new Agilent Community Group, GPC/SEC Solutions Group is hosting a webinar series in partnership with Dow in April: A Journey through SEC, Light Scattering, and 2D-LC for Macromolecules…
The Background values are so called "off mass background".
This could indicate an electronics or contamination problem of the quad.
In your case, the values are still quite ok.
I would guess, one of the lenses has a setting which is causing this…
Hello everybody!
We have the issue that in our run (ca. 100 - 200 samples, 7 min each) for like 20 samples there is no signal, just the technical background noise. Not even the peak that is in the Blank appears. An the it sowly comes back over 2 samples…
Hi,
Apparatus 4 is the only USP Apparatus Agilent doesn't make. I would recommend reaching out to an App 4 vendor for support based on how you're using it (open/closed loop, sampling volumes, etc. that need to be considered). If we can help you with…
Yo tengo también una consulta sobre el software. Cómo podría volver a leer una muestra sin que se distorsione el informe al momento de imprimirlo? Y sin tener que volver a calibrar.
Your vial's cap is loose or deformed?
Many crimping and de-capping problems can be solved by two very general suggestions:
Verify the cap is properly crimped
Adjust the electronic crimper/de-capper as necessary
Verify the cap is properly…
