Shim-pack Velox C18
HPLC Column
C18
Shim-pack Velox C18 is a traditional end-capped C18-bonded phase which offers the highest hydrophobic retention of any Shim-pack Velox phases and is applicable to a wide range of applications such as pharmaceutical, food, environmental and clinical and neutrals at moderately low and mid-range pH.
- General purpose column for reversed-phase chromatography
- Highest hydrophobic retention among Shim-pack Velox series
- Compatible with moderately acidic to neutral mobile phases (pH 2-8)
Method Transfer for Cyanocobalamin Analysis within the USP Allowable Adjustment
The assay of cyanocobalamin (a synthetic form of vitamin B12) with 5 μm fully-porous ODS column described in the USP monograph is transferred to a new method with Shim-pack Velox C18 2.7 μm column, within USP allowable adjustments. Analytical time and solvent consumption can be saved with transferred methods while meeting the requirements of system suitability.

Biodegradable Plastics
In order to reduce plastic waste, the development of eco-friendly alternative materials is being promoted. As an alternative, biomass plastics and biodegradable plastics are becoming more widely available. Biodegradable Plastics are plastics that are decomposed into low-molecular compounds by microorganisms in the environment. So they break down easily in nature, which is an opposite characteristic of petroleum-based plastics.

Shimadzu has released the Nexera lite inert
Nexera lite inert is a robust HPLC system that eliminates the risk of corrosion by high-salt mobile phases and sample adsorption onto metal surfaces. It improves the data quality of protein analysis in biological samples with superior reproducibility, without any special considerations for stable and long-term use.

Shimadzu has updated the i-Series, High Performance Liquid Chromatograph
Amid increasing calls for improved work efficiency and a more flexible working style, ideas of LC analysis are changing. The time has come for an HPLC that delivers rugged, reliable results with less frequent interaction by the analyst. The new, integrated i-Series LC system maintains the excellent performance of its predecessor while addressing the need for automation efficiency.
