            your website...It has helped me
              significantly...."
 " ... very useful for
          teaching in an Instrumentation course for M.Sc postgraduates
          in analytical chemistry. 
        
"[Y]our web site has such excellent content...."
"I tried the demo version of SPECTRUM and I think is a very useful tool for the introduction of signal processing to analytical chemistry students."
