Our laboratories have all the necessary equipment to satisfy the needs of our customers and to accomplish the deadlines that are so important to us.

Among all the equipment of Docuchem the following ones stand out:

LC-MS (Shimadzu 8050)

Coupled with one of our UHPLC system, we have our Mass Spectrometer detector Shimadzu 8050. It is based on a triple quadrupole which provides very sensitive analysis and it has APCI and ESI ionization sources.

LC with Charged Aerosol Detector (CAD)

LC equipment with Charged Aerosol Detector (CAD), with detection capacity for a wide range of non-volatile and semi-volatile analytes, offering a uniform response that allows precise quantification of them.


Shimadzu – Nexera X2 UHPLC and Shimadzu – iProminence LC 2030 HPLC systems.

We have the following detectors available in our UHPLC systems:

  • PDA detector
  • Triple quadrupole MS detector
  • RID detector
  • ELSD detector
  • Fluorescence detector
