$485.00 / Each
Add to Favorites ( Item Number SRM-HO )

Precision Cells Holmium perchlorate (4% w/v) in 10% perchloric acid (v/v). This corresponds with the European Pharmacopoeia requirement for 40g/L holmium oxide in perchloric acid containing 141g/L of HClO4. This wavelength standard is provided in a quartz cuvette to ensure optimal calibration.

All PC calibration standards are NIST traceable and NIST compliant. Performance of all PC reference calibration standards, including but not limited to this standard, meet or exceed NIST requirements.

Recalibration of PC liquid calibration standards are periodically required as per NIST guidelines. PC will provide periodic recalibrations accordingly. Please contact us for more information.
Wavelength Peaks

The PC Homium filter is used to calibrate wavelength accuracy in the 240-650 nm range.

The PC Holmium wavelength filter has the following peaks:  (see chart below)

  • 240.8
  • 277.8
  • 287.1
  • 361.1
  • 416.4
  • 451.2
  • 485.2
  • 536.5
  • 640.5

Please note that this is a liquid calibration filter and does not come with the same Lifetime Warranty as PC's Solid State Standards.  The PC liquid holmium filter must be recalibrated every year according to NIST guidelines.

For customer interested in our solid state Holmium filter that never requires recalibration due to material aging please see the link below.
