CAN TEMPERATURE CONTROL ENHANCE LC PRECISION? If you are using anything other than the BAS 200 Problem Solver™, you may not know the answer. With the BAS 200 you would have an advanced temperature control system which can accommodate both electrochemical and UV detector cells, most column formats, and the injection valve. The result? Enhanced precision, lower baseline drift, improved symmetry and results beyond anything you could expect from a modular LC system. This unique approach to temperature control is only one of 20 great ideas incorporated into the hot, new Problem Solver™ from BAS.
