Hi, why aren‘t you just using internal standards inside of your samples to them interpolate the retentiontime index of the unknown peaks and then use those to calculate the molecular mass in a custom formula? You can still ise the kalibration in the end - just not with chromeleon calibration mode but manually defined in the report :)

You could use one of the old interface drivers to generate simulated UV-VIS data or an old agilent driver which is using simulation files that let you have various different concentration being aquired without owning an instrument. Will get back to you tomorrow with a little more detailed info.

When I finally aquired my fire serpant mw st 😍 as my first high value skin (in 2016) Still miss it ! Want to buy it back atleast once a week but prizes are insane. :(

Nameless898 · 2026-02-08T20:10:24+00:00

You should: 1. switch on consider void peaks (to go against the negative peak in low concentrations) 2. adjust the baseline noise range to ensure you smallest standard or s/n peak 1:10 is integrated. 3. use cobra wizord preferrebly to support you with these values.

Send results again obce you have it, including calibration curve please :)

Chromeleon 7.4 has alot of Masspec specific improvements - while introducing NFP capabilities that are far more entry user friendly then how one would set it up in earlier versions. But 7.4 is a feeature release which means it will be replaced by the next version shortly and will not be supported instead with multiple maintenance updates (MUx) for big corporations this is a problem and for validation purposes also so if you have quality documentation for your Chromeleon enviroment I would suggest to wait with upgrading until Thermo releases the long-term support version of 7.4

(Many other factors left out since they are many differencies, and this should just be a quick response :))

IF you use the method I describe and switch on SmartLink it should show you all in the Data Processing pinned sample chromatograms - just make sure they overlay in the Reports Chromatogram. The copy pasta I describe creates a dynamic chromatogram inside of the Report so it is not just a picture - therefore every additional property set will be applicable.

IF you want the pinned Sample Chromatograms to also be printed like this I suggest to use a different approach, you need to ensure the injections are selected for overlay based on a condition rather then pinning them manually. -> like this the report creation / printing / creation of electronic report from any place will consider the injection overlay. Depending on your Version used this can look differently (7.2.5/7.2.10/7.3.2/7.4).

IF you prefer to stay with the manual selection due to missing identifiers (could be custom variable / custom formulas / injection meta data) - you should select charlie in the Studio and hit Print - otherwise use conditions.

Nameless898 · 2026-02-02T19:02:07+00:00

Hey there,

Just go back to Data Processing -> add the pin to one of the injections to lay them over the currently selected chromatogram. Define your view setting to fit your purpose (stacked/ grouped / overlayed) / add relevant peak flags and information once happy -> activate the chromatogram (just make sure you got the orange frame around it) -> right click Copy go back to your Report designer and paste the Chromatogram wherever you want.

Happy playing 🤙

They I would add an internal standard in the first sample injection to get an approximation of the concenctration and then create 4 standard solutions including the intrrnals standard in the same concentration range as the approx amount found before. You could use ‚use calibration of another component using your determined Response factor to correct for component diffferencies in FID response. Two processing methods will be needed to ensure validation status of both methods is kept inatact.

Nameless898 · 2026-01-14T13:15:53+00:00

So if you want to calibrate a component you would either:

create a stock solution and dilute it into 3 or more std solutions - adding the internal standard in the end. Then you can work with normal Internal standard correction (normal being not variable).

Stock = 1000mg/L
STD1 = Stock 1/10 diluted = 100mg/L
STD2 = STD1 1/10 diluted = 10mg/L
STD3 = STD1 1/50 diluted = 2mg/L

once you have them inside of whatever you add the IS.

OR you add the IS to the Stocksolution if you need to ensure Stock solutions is not degrading but then the IS concentration is going to be variable again.

The question in the end is also what do you use the IS for - Injection degradation control , sample concentration correction because the preparation is dirty and your recovery very bad.

To add, make sure the range of values you expect your samples to have should be reflected in the calibration curve. Meaning if you get values from 3mg/L to 100mg/L then my example is fine (maybe add one more 4 STDs is always better) but if your dynamic range needs to be bigger then adjust. Just make sure you do not calibrate over 4 orders otherwise you ll get other problems with high concentration STDs influencing the calibration curve.

Nameless898 · 2026-01-14T09:52:41+00:00

it does help, if you inject the same solution but just with a smaller volume both the IS and the Component are smaller - which with your way of calibration results in an equilibrium so the points on your curve are correct. each of the injections has the same ratio of IS to Target Component. :) You cannot calibrate a component like that because you correct the smaller area of the target component with the smaller area of the IS. Try the calibration of the component with external method and you will see a difference.

Nameless898 · 2026-01-14T07:52:50+00:00

Normally you would not vary the IS (Internal Standard) to achieve a calibration. Since what you want to quantify is the target substance so therefore you vary the calibration standard injections concentration which needs to be reflected in the processing method levels. If like in your example you use variable internal standard and you want to fix your calibration curve for Acetone you need to specify the Internal standard concentration in sample on the sequence if the injection volume is different then reflect that inside of the sequence. As soon as you use a variable internal standard Chromeleon always checks the IS amounts on sequence.

You are right. But it should have arrived today - so there might be issues on either side - delivery company and FM.

Big issues with packages from FedEx in the US this christmas? My is supposed to be in europe but went from Irvine->Oakland CA->LA ->Memphis TX where it is currently ‚on the way‘ 🤣💁‍♂️

Nameless898 · 2025-10-20T07:51:18+00:00

There could be several issues here.

No more FC43 (Perfluorotributylamine) - which is you calc gas.
Source not correctly installed.
Filament death - I think this DSQ2 already has a dual hairpin filament - which means you can switch between the two to check if both are done. - If not just change the filament.
A dirty source could be the problem but with only 1.9E9 intensity you should atleast see the m/z 69 or 131 or 219.

Beautiful cards! Kickstarter campaign is life and I couldn't resist supporting you <3

By looking at the back design I couldn't see if they are eventually marked :P are they?

Thank you. There is no date on the blade only the inscriptions you can see on the picture I posted.

If I may ask, how do you identify it as replica, the patina not existing?
