If you are a new CMSP customer, please contact Candace Guerero (cguerrer@umn.edu) or LeeAnn Higgins (higgi022@umn.edu) to gain access to the CMSP Portal.

Client Portal Quick Instructions. Sign into VPN. Go to the Client Portal, type your X500/Internet ID in the Account Name field (not your full email address!) and enter your UM Password. Click on "+ New Experiment" button on the client portal. Fill in the pertinent fields and be sure to select the desired EFS string from the drop-down list. If the desired account is not in the list, cancel the submission and submit a valid EFS string from the Pending page. Please fill out samples names and a description of the analyses you request. Please add additional attachments and/or project backgrounds. Refer to the Help document for further details.

After New Experiment initiation, a temporary "Experiment Number" will be listed in the "My Pending Experiments" section and you will also receive an email with the Temporary Log number.

Reserve a time on the appropriate CMSP sample drop-off calendar before you deliver samples. Email or call to ensure CMSP personnel will be in the lab to receive your samples. If you're not sure where your samples should be delivered, please contact the lab. 

Sample turnaround time is dependent on the current sample queue and other factors, including instrumentation status (e.g., maintenance schedules).  Customer participation in sample preparation procedures is encouraged after proper instruction from lab staff.  Contact core facility staff for inquiries on sample status.

NOTE: All samples are analyzed in the order of receipt.
