Vario EL cube is used for detecting the content of CHNSO elements in the samples of chemicals, drug synthesis monomers and polymers. Vario EL cube has unparalleled durability, provides reliable elemental analysis results, and is an introduction to elemental analyzer. It uses elementar's advanced scavenging technique to obtain good gas separation results using a program desorption column (TPD).The analytical column can analyze the sample of C/N ratio up to 5000:1, and ensure the separation of the baseline.
