The information makes the center measure a CHN analysis in a optimal way. For example, the center can add a combustion improver in the case of the sample which contains alkaline metals, alkaline-earth ones, F, Si, Se, or P elements. Please write the structural formula on an application form as far as you know about it.

"2 times of CHN analysis" means that the center carries out 2 times of measurements unless there are exceptional circumstances. "1 time of CHN one plus reanalysis" means that the center measures 1 or 2 times depending on criteria for judgment of reanalysis. We recommend "2 times of CHN analysis" when you want to know average CHN content percentages of heterogeneous samples or you determine composition of unknown compounds by using CHN analysis results.

The center will provide information of ones if you mention on your application card. However the center can't measure weight of the residues in case of adding a combustion improver (see A1). If you prefer to know the weight of residue, please write the demand.

Yes, the center will keep them in the refrigerator/freezer right up to CHN analysis if a client brings them to the center.

Although it takes at least 2 minutes to prepare for measurements under air, the center will treat the samples quickly wherever possible. An appointment in advance helps the center perform that kind of difficult analysis.

No, it accepts only CHN analysis.
