供应商: VWR Chemicals
描述: Ethanol 96% (v / v), AnalaR NORMAPUR® 分析试剂
供应商: HICHROM
描述: Avantor® Alltima HP columns features for general purpose normal-phase applications.

供应商: Avantor
描述: J.T.Baker® volumetric and analytical solutions. These solutions are suitable for use in ACS, USP and NF compendial methods and general laboratory applications. 
供应商: HICHROM
描述: Prevail™ HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. All phases, apart from Prevail™ Carbohydrate ES are silica-based. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes.

目录号: (VWRC24127.237)
供应商: VWR Chemicals
描述: 氯化铁(II)四水合物 98.0-102.0%, AnalaR NORMAPUR® analytical reagent
计量单位: 1 * 250 克

SDS 证书


供应商: VWR Chemicals
描述: 磷酸氢二铵 ≥98%, AnalaR NORMAPUR® Reag. Ph. Eur., ACS analytical reagent
供应商: VWR BRAND PRIVATE LABEL USA
描述: 用于分析重量

供应商: Avantor
描述: Avantor® ACE® Excel® C18-Amide is a uniquely designed stationary phase offering improved retention of polar compounds, enhanced phenolic resolution and alternative selectivity to C18 bonded columns. These stainless steel columns are available in a wide range of particle sizes and dimensions from capillary to preparative.

目录号: (VWRC22604.153)
供应商: VWR Chemicals
描述: 硫酸铈(IV)四水合物 ≥98.0% analytical reagent
计量单位: 1 * 50 克

SDS 证书


供应商: VWR Chemicals
描述: Mixture of metaphosphoric acid and sodium metaphosphate (NaPO<sub>3</sub> : 56 to 60%)
目录号: (VWRC21645.124)
供应商: VWR Chemicals
描述: 偶氮甲碱-H analytical reagent
计量单位: 1 * 10 克

SDS 证书


供应商: Avantor
描述: Avantor® ACE® CN-ES combines CN polar selectivity with enhanced hydrophobicity, enabling the benefits of both interactions to be fully exploited. Extra phase stability and increased column lifetime is provided by an extended alkyl chain spacer between the silica surface and cyano group. Avantor® ACE® CN-ES is suitable for both reversed phase and normal phase separations.

供应商: HICHROM
描述: Saturation columns are placed between the pump and the injector and they saturate the mobile phase with silica, minimising dissolution of the analytical column when working above pH 7.

供应商: Avantor
描述: The Avantor® ACE® Excel® C18-AR phase utilises a specially developed ligand combining a C18 chain with integral phenyl functionality, thus combining the benefits of both C18 and phenyl characteristics into a single phase. This can be used for ‘standard’ C18 column separations, but is additionally recommended for separations that involve compounds containing aromatic functionality.

供应商: VWR Chemicals
描述: 硫代硫酸钠五水合物 99.5-100.5%, AnalaR NORMAPUR® ACS analytical reagent
供应商: VWR Chemicals
描述: High quality CCS viscosity standards are ideal for the calibration and verification of analytical equipment used in Cold Cranking Simulator (CCS) testing.
