Retention Times :
The retention times chart is a partial listing of the retention times of common organic acids tested on Benson Polymeric columns using
typical test conditions (0.6 ml/min, 60o Celsius, 0.01 N sulfuric acid). The retention time of organic acids can be influenced using acid
strength, temperature, and column choice. By choosing the proper combination of the test conditions and column, your sample separation
will be optimized. For specific recommendations on the column and test conditions best suited to maximize your particular sample please
