i'm looking for a chemical test for the purity of the drug's
ativan(lorazipan, it's generic) and a tricyclic "geodon". Does anybody
out there know how to test these drugs for their purity. ativan 1mg.
geodon 80mg.

A reliable test of a drug's purity can only be performed in a
specialized laboratory, and will come out costly - possibly several
hundred US dollars.  Will you accept references to a laboratory that
can perform the tests for you, or are you looking for a description of
the relevant methods?  You will *not* be able to perform these tests
yourself without access to advanced laboratory equipment.

yes, laboratory references will do.  particularly in the san francisco, bay area.

Hello again, drzander,

I am sorry for the delay in answering you - the question is trickier
than I thought.  I have finally located an independent drug analysis
laboratory that has a representative in San Fransisco.  I believe that
they can help you, but the lab need to discuss your exact analysis
requirements.

We can solve this in two ways - I could post the contact information
for this lab as an answer, or we could discuss the details of the
analysis process here.  Please advice me how you wish to proceed.

If you can give me the details and the lab information that would be great.

I apologise for being a bit unclear in my previous message.  To decide
what kind of analyses the lab should perform on the drug samples, you
will need to discuss quite a few details with the laboratory.  The
following information would be useful for them:

 - What is the origin of the samples?
 - You have stated that you wish to test the purity of the drugs.  Are you
   concerned about any particular impurities?  (It could be hard to detect an 
   impurity if you don't know what you are looking for...)
 - What is most important; to confirm the presence of certain compunds, or to 
   confirm the absence of some other compunds?

The lab will possibly need even more information before starting the
analysis process.  I suggest that you discuss these matters directly
with the lab's San Fransisco office.  If this is OK with you, I will
post the contact information for the lab as an answer and leave the
negotiations about the analysis to you.

Alternatively, you could post the details of your request in this
forum so that I can forward them to the lab.  I will then post the
reply from the lab here.  Please note that this will be quite
time-consuming compared to calling or e-mailing the lab directly. 
Also, such communications between you and the lab can be read anyone
reading this public forum.

Please tell me if you wish to contact the lab yourself now, or if you
wish to dicuss the matter further in this forum before I post the
lab's information as an answer.

I have located a laboratory chain that should be able to perform the
lab tests you are looking for - Intertek Caleb Brett
(http://www.itscb.com/).  They have a webpage listing some of their
laboratory services at
http://www.itscb.com/newsitetest/whoweare/labtesting.shtml .

The lab's contact information is:

Intertek Caleb Brett
California Technical Center
6050 Egret Court, Benicia
California, 94510

Email: testingservices@itscb.com

Tel: 707-746-0556
Fax: 707-745-1123

I have been e-mailing with the Laboratory Director at Intertek Caleb
Brett's San Fransisco office, Mr Wayne Britton.  I suggest that you
contact him to discuss your exact analysis requirements.  His e-mail
addresses are wbritton@itscb.com and Wayne.Britton@intertek.com.  You
might also try to phone him directly at 707-373-7129.

I believe that you will be able to find a useful procedure for solving
your problem.  Please note that I cannot guarantee that Intertek will
be able to provide the service you want at aprise you can accept - as
I mentioned, qualitative analysis can turn out to be very expensive.

I hope that this answers helps you solve your problem.  If not, please
request an answer clarification before you proceed to rate my answer.


Search strategy:
I started searching for San Fransisco laboratories that could provide
the services you requested, using this search term on Google:

  laboratory "pharmaceutical analysis" OR "drug analysis" "san
fransisco" OR "bay area"

Among the results were a few labs that seemed to be able to help you. 
I e-mailed them with your questions.  Only Intertek answered that they
might be able to help you.  As outlined in my question clarification
requests, it will be best if you discuss directly to find the best way
of determining the contents of the drugs.
