EIC report with smaller chromatogram to reduce the number of pages in the report

Hello,

Try the MS Chromatogram Flowlayout object instead of the individual chromatograms.

Hi Martin. I have the same problem. I don't know how to manage the group repeating so we can have different compound name on chromatogram lighted in gray. 

Hello,

All the multipliers are used in the concentration calculation. The multiplier in the method is the compound multiplier which is different from the sample multipliers 1-5.  The compound multipliers can be different for each compound in the peak table but are the same for all injections. The sample multipliers are applied to all results for a given injection but can be different for each injection

Marty. 

I'll do a little digging to see if I can find the field name. I've never had to reference this before so I'm unsure if you even can. I'll reply back if I find something

It's weird because I don't have this option on my side. No Multiplier. 

In my version, that field isn't available. However, he can get it by the calculation =Compound_Concentration/Compound_Amount

I don't have the multiplier field either on my openlab CDS 2.6. 

I don't understand your calculation to retrieve my multiplier of 10. 

if I use your equation with my first example it will be : 

393.60 ug/g divided 9.84 = 40. It doesn't work. it's supposed to be 10. 

Does it return exactly 40? If you pump up the number of decimals is it 40.000000000? If so, then it's probably using one or multiple values you entered somewhere, which would allow you to modify the calculation to account for that. At least on my end it just spits out the multiplier, but I also doubt I have all the same stuff filled out as you do.

Did you enter a 4 somewhere? Or a 0.25?

My equation is : 

ug solvant/g samples= amount/sample weight (mg) * 100 *10 

In bold view, this is calculated with the % mass formula. the multiplier 10 is the one I want to show on my sequence table summary. 

Try the calculation I stated above in the software and let me know what it returns. I can't really help unless I know what it returns. If you do calculations by hand, there is no guarantee you're doing the same calculation as the software would. If it returns exactly 40 when put into the software, then look around in your other entered fields for 4 or 0.25. I expect it would be in the multipliers or dilution factors.

your equation do not involved the sample weight and the 100 multiplier. in that case, sample weight is 25 mg. So 100 divided by 25 gives 4. 

It will be easier to know why I don't have the multiplier showed by Martin. 

Do we need openlab CDS 2.7?

I have openlab 2.7 and it's not there either. I expect it was added in a future update. Not much you can do unless you already have the licensing to upgrade or you can convince your company to buy it. I've already tried directly referencing it manually. It doesn't recognize as a variable in my version. The only other real options are to reference it another way (I don't know of one) or to calculate it using things you can reference, which is what I'm attempting to do.

I will be hard to do it like you want. 

Multiplier = (Concentration in ug/g * sample weight ) / (Calculated amount *100)

Since I put sample weight only on samples, we may have problem if we have zéro for other injection type in the sequence table. 

Have you tried the formula in the software yet? From my side it looks like Compound_Concentration is the calculated concentration and Compound_Amount is the calculated amount both based on the curve. It looks that the curve calculates the compound_amount, then simply multiplies by the multiplier to get the compound concentration. If this is how the software does it, then the formula will work. I've already tested it on my end and it works (with sample amounts of 0 throughout the sequence). If it doesn't work for you, then I'm fairly certain we can figure out why, but we won't be able to do anything without knowing what it does for you
