Hi friends.!
I m using GCMS QP2010 shimadzu and i m going to analyse phthalates in this system.
The peaks of DINP( Di iso nonyl phthalate) and DIDP( Di iso decyl phthalate) are like fringes( finger prints).
My question is how to calculate the concentration and area of this fringes manually. As some time we have sample with both DINP and DIDP with almost same retention time. and they got overlapped with each other.
The colum length is 30m,dia=0.25,thicknes=0.25
split ratio=20
ion source temperature=250C
temperature programe=2.5-15 min
please help me to resolve this problem.

Shimadzu has phone support available to help you with your questions.
You need to send them a data file. I don't think it is possible for them to understand what you are describing verbally. You can find their Customer Service for the U.S. on the web. If you are a Shimadzu customer you should know someone who can get you in contact with Customer Service. They can have someone contact you and when you send them a data file they will have the best chance of understanding your "problem."

Thanks quadrpole.
I have sent a request to shimadzu coordinater.lets see what happen now.
