Johan Gustav Christoffer Thorsager Kjeldahl (] 16 August 1849 – 18 July 1900), was a Danish chemist who developed a method for determining the amount of nitrogen in certain organic compounds using a laboratory technique which was named the Kjeldahl method after him. Using only the above description and what you know about the world, "The method to determine the amount of nitrogen in certain organic compounds was developed by a chemist in a laboratory a long time ago." is definitely correct, incorrect, or inconclusive?
