Solvent Information
Material Information
Materials in the flow path are carefully selected based on Agilent's
experiences in developing highest quality instruments for HPLC analysis over
several decades. These materials exhibit excellent robustness under typical
HPLC conditions. For any special conditions please consult the material
information section or contact Agilent.
Disclaimer
Subsequent data were collected from external resources and are meant as a
reference. Agilent cannot guarantee the correctness and completeness of such
information. Data is based on compatibility libraries, which are not specific
for estimating the long-term life time under specific but highly variable
conditions of UHPLC systems, solvents, solvent mixtures and samples.
Information can also not be generalized due to catalytic effects of impurities
like metal ions, complexing agents, oxygen etc. Apart from pure chemical
corrosion, other effects like electro corrosion, electrostatic charging
(especially for non-conductive organic solvents), swelling of polymer parts etc.
need to be considered. Most data available refers to room temperature
(typically 20 – 25 °C, 68 – 77 °F). If corrosion is possible, it usually accelerates
at higher temperatures. If in doubt, please consult technical literature on
chemical compatibility of materials.
PEEK
PEEK (Polyether-Ether Ketones) combines excellent properties with regard to
chemical resistance, mechanical and thermal stability. It is stable in a pH
range of 1 to 12.5 and inert to many common solvents. There are several
known incompatibilities with chemicals such as chloroform, methylene
chloride, THF, DMSO > 1 %, strong acids (nitric acid > 10 %, sulphuric acid >
10 %, trichloroacetic acid, sulfonic acids), halogenes or aequous halogene
solutions, phenol and derivatives (cresols, salicylic acid etc.). When used
above room temperature, PEEK is sensitive to bases and various organic
solvents, which can cause it to swell.
