Medchemexpress LLC Iohexol (Standard) | 66108-95-0 | 99.2% | 50 MG
Iohexol (Standard) is the analytical standard for Iohexol, intended for research and analytical applications. It functions as a non-ionic, water-soluble contrast agent. Iohexol is utilized as a reference marker to determine the glomerular filtration rate (GFR) at the renal function level. Additionally, it can be employed for contrast in various imaging procedures including myelography, computerized tomography (cisternography, ventriculography), and MicroCT imaging.
- Analytical standard for Iohexol
- Non-ionic
- Water-soluble contrast agent
- Used as a reference marker for glomerular filtration rate (GFR)
- Applicable in myelography, computerized tomography (cisternography, ventriculography), and MicroCT imaging
- Suitable for qualitative, quantitative, and methodological research experiments in HPLC, GC, and MS
Electron Microscopy Sciences MXS Calibration Standard 701CE for SEM Unmounted, 700 nm Spacing
EMS offers a series of calibration standards with one and two dimension calibrated patterns. These standards are created utilizing holographic interference of a particular laser frequency. They are typically accurate to <1% across the entire surface of the standard. These reference standards are remarkably durable under typical operating conditions. The surface contamination behavior is also very good. There are no better sub-micron reference standard available in this price range. For SEM
Mount: Unmounted
Spacing: 700 nm
Structure: Parallel Ridges
Material: W-coated Photoresist on Si
