zNose® Detects Melamine in Milk Powder in Record Time

  
    
  
  
    
      Electronic Sensor Technology (EST) (OTCBB:ESNR), 
      a leading provider of innovative homeland security and environmental 
      solutions, announced it has developed a procedure for detecting melamine 
      in milk powder using the fast zNose®.
    
    
      Dr. Teong Lim, Chairman and CEO, reports that a method for detecting and 
      measuring melamine without the need to derivatize or modify the sample 
      has been created. Current cost per sample range around $120 in the US to 
      $145 in China. The FDA method (Bulletin No. 4423) requires 85 minutes of 
      preparation before the 20 minute GC-MS run. Even the fast-screen method 
      (LC/MS) takes 14.5 minutes after sample preparation. EST’s 
      method does not require this preparation time and can do a sample run in 
      less than 3 minutes. This significant savings in time will reduce sample 
      testing costs by using the zNose® as a 
      prescreening tool. Only samples that indicate melamine are subjected to 
      the costly testing methods.
    
    
      The presence of melamine in milk powder has been linked to over 53,000 
      infant illnesses and 4 infant deaths as well as pet food problems and 
      egg contamination. The use of melamine to cheat the nutrition tests has 
      been a practice in many areas and there is no way to contain the 
      contamination without the use of detection tests. Reducing the time and 
      costs of the test with the use of the zNose® 
      could help save infants from illness and more.
