On behalf of the Organizing Committee, it is indeed a great honor and pleasure to invite you all to the 4th Asian NIR Symposium (ANS 2014), which will be held on June 17th to 20th, 2014, in Daegu, Korea (http://www.ans-2014.org, will be activated around middle of Oct. 2013). ANS 2014 aims at highlighting and treating in-depth recent developments and progress in the field of Near-infrared (NIR) spectroscopy. NIR spectroscopy is a fast and versatile method that able to analyze diverse samples non-destructively without sample preparation. Research and techniques that utilize NIR spectroscopy will be topics of the conference. The conference will cover all aspects of NIR spectroscopy ranging from the theory to applications in various fields, such as agriculture, polymer, pharmaceuticals, chemicals and on-line quality control. Not only solely NIR spectroscopy, but also any other hyphenated analytical methods with NIR spectroscopy could be included. Your active participation in the ANS 2014 will certainly make a successful conference. Please mark your calendar - the ANS 2014 from June 17th to 20th, 2014 in Daegu, Korea!
