hi guys, first time posting.

I need some guidance to prep. a std sol. and working std for 4-chloroaniline which have a range of 1ppm, 10ppm, 50ppm and 100ppm. The instrument ill be using is HPLC-UV with C18 column, and ill be using acetonitrile and water as the mobile phase.

OK, so what's the question.  You've given us some information, but not all of it is pertinent.  Can you show us how you would begin?  How would you make a 100 ppm solution?  Do you know the definition?  What techniques do you know for making these dilutions?  I mean, glassware techniques.

This forum has rules, we like to see a bit more work from High School and undergraduate students, we don't just dump complete answers.  We even hold our Citizen Chemists to a high standard, we like them to provide us with questions that contain a complete thought, and we want them tobe open to discussions of chemical concepts.  We don't respond well to "gimmie gimmie" questions.
