Measuring Acid Profile in Plating Both Solutions
Novel Cationic Polymer Coated Capillary Column
Metrohm UK has developed ion chromatography methods for the measuring the acid profile of the different acids usually
present in typical plating bath solutions; usually HF, HNO3 or H2SO4 or a combination of. The method requires nothing more elaborate than a simple dilution followed by injection into the 883
Basic IC plus from Metrohm with typical analysis times of less than 20 minutes. The intuitive nature of the MagIC Net Basic software means that the instrument can be run by a shift operator with literally a few mouse clicks. Historically the plating bath analysis was often performed using a manual wet titration to determine the acid content which was often subjective for semi- skilled personnel and open to errors and costs. Ion chromatography is a robust technique that allows for more accurate and tighter control over the profile of acid content that usually results in considerable cost savings as the bath is more carefully controlled and necessary acid additions made only when required. Plating bath solutions are used typically in many industrial processes as a final cleaning stage prior to plating and remove the surface oxides and other contaminants. In addition, the metal surface is activated ready for plating and a light etch is achieved that helps provide a better adhesion to the substrate material.

New Chiral Stationary Phase — CHIRALPAK®
ID™
Chiral Technologies announces the availability of a new immobilized chiral stationary phase (CSP), CHIRALPAK ID. This CSP is the fourth addition to Chiral Technologies’ family of immobilized CSPs. This new selector provides a novel enantiorecognition mechanism and is highly complementary to the three previously introduced immobilized CSPs: CHIRALPAK IA, IB, IC. The addition of this immobilized CSP signals an even greater success rate in addressing very challenging enantiomer separations. CHIRALPAK ID, as all polysaccharide-based Daicel phases, can be used in both high-performance liquid chromatography and supercritical fluid chromatography modes. Use of the current set of immobilized CSPs will afford exceptionally high success rates in identifying the best method for separating chiral compounds, while screening with fewer columns and mobile phase combinations.

NACALAI TESQUE introduces COSMO(+)Capillary for Capillary Electrophoresis. COSMO(+)Capillary is a cationic polymer coated capillary column. Electroosmotic flow (EOF) is from the cathode (-) to the anode (+) because of the cationic polymer coating inside of the capillary column. This novel capillary column provides high reproducibility, fast analysis and is operable over a wide pH range (pH 2-10).
