ND15 8ml HPLC Vials

These vials are recommended for short term sample storage and non-volatile samples because the seal is not as secure as a crimp or screw thread seal. Shell Vials are an economical alternative to screw thread vials for Water’s HPLC autosamplers or any other autosampler that doesn’t use a robotic arm to move the vials.

Proper Vial Closure Techniques from Aijiren

Jun 22,2020· Closures should be screwed on securely but not over-tightened. Over-tightening may causeSeptum distortion-when placed under too much pressure the septum can become twisted inside the cap,leading to re-sealing problems and coring on injection. Unscrewing-an over-tightened cap can actually unscrew itself resulting in sample evaporation.

Peak Tailing in HPLC-Crawford Scientific

Assess this by simply diluting the sample x10 and re-assess the peak shapes in the resulting chromatogram. If necessary,use a higher capacity stationary phase (i.e. increased % carbon or pore size),use a column with an increased diameter,or decrease the absolute sample amount or volume injected. Consider the possibility of column bed deformation
