This refurbished Shimadzu TOC 5000A Total Organic Carbon Analyzer includes the ASI-5000A autosampler. This system will come as-is.
We have special expertise on analytical equipment. We encourage you to contact us to speak with one of our expert and professional team members.
Thanks for looking and we look forward to hearing from you!
| Analyte | TC, IC, TOC (TC-IC), NPOC (non-purgeable organic carbon), POC (purgeable organic carbon: option)Method Combustion/non-dispersive infrared gas analysis method) |
