Basics of Ion Chromatography: The Flow Rate of the Eluent Affecting Separation

Basics of Ion Chromatography: The Flow Rate of the Eluent Affecting Separation

A clear explanation of the basics of ion chromatography! Let's understand how changes in the flow rate of the eluent affect separation.

Ion exchange separation occurs due to the competition between the measurement ions and the eluent ions on the ion exchange sites. One of the factors that affects this ion exchange separation is the change in the flow rate of the eluent. I will explain the differences in the chromatograms obtained by varying the flow rate of the eluent and the points to be cautious about.

Basics of Ion Chromatography: Temperature Affecting Separation

Basics of Ion Chromatography: Temperature Affecting Separation

A clear explanation of the basics of ion chromatography! Let's understand the impact of changes in column temperature on separation.

Ion exchange separation occurs due to the competition between the measurement ions and the eluent ions on the ion exchange sites. One of the factors that affects this ion exchange separation is the change in column temperature. When the column temperature is altered, the retention time of the measurement ions changes due to variations in separation equilibrium, diffusion rates, degree of dissociation, and the viscosity of the eluent. The impact of temperature varies depending on the type of measurement ions and also changes with different columns and eluents. This factor of temperature will be explained.

[Analysis Case] Risk Assessment of Nitrosamines in Pharmaceuticals

[Analysis Case] Risk Assessment of Nitrosamines in Pharmaceuticals

[Introduction to Ion Chromatography Cases] Measurement of Nitrite and Amines

N-nitrosodimethylamine (NDMA) is an organic compound represented by the chemical formula (CH3)2NNO. NDMA is a known carcinogen found in some fermented foods. The measurement of nitrite ions can be performed using wet chemical analysis, but a representative method in instrumental analysis is ion chromatography (IC). In IC, separation is achieved using an ion exchange column, and detection is carried out using conductivity detection, electrochemical detection, UV detection, or mass spectrometry. Methods using IC typically require little to no sample pretreatment for many pharmaceutical samples, and derivatization of the target components is also unnecessary.

[Case Study] Analysis of Tocopherols α, β, γ, and δ using 2D-LC

[Case Study] Analysis of Tocopherols α, β, γ, and δ using 2D-LC

Vitamin E (alpha, beta, gamma, delta tocopherols) in vegetable oils can be separated and quantified without the influence of interfering components using single-loop heart-cut 2D-LC.

This document introduces a method for the high-precision separation and quantification of four types of tocopherols contained in vegetable oils using the single-loop heart-cut 2D-LC method. Under the separation conditions of a reverse-phase system using a general ODS column, the separation of β-tocopherol and γ-tocopherol is difficult; however, the 2D-LC method allows for easy separation. In the first dimension, tocopherols and interfering components in the sample are separated, and in the second dimension, the four types of tocopherols (α, β, γ, δ) are separated. The repeatability of the standard samples achieved a high reproducibility with RSD < 0.1%. Additionally, measurements conducted on multiple vegetable oils showed that quantification was possible without the influence of interfering peaks. The single-loop heart-cut 2D-LC method is the simplest technique among 2D-LC methods, making it applicable for routine analysis and a useful tool for food analysis involving samples with a high content of matrix components. 【Features】 ■ High-precision separation achieved with the single-loop heart-cut 2D-LC method ■ Separation of β-tocopherol and γ-tocopherol, which is difficult in reverse-phase systems ■ Effective separation of interfering substances in food ■ High reproducibility with repeatability of RSD < 0.1%

Scalable purification of full capsid AAV by chromatography.

Scalable purification of full capsid AAV by chromatography.

Introducing a scalable AAV purification process and a method for separating full capsids and empty capsids using anion exchange chromatography.

Adeno-associated virus (AAV) is widely used as a vector for gene therapy. While it is often purified using ultracentrifugation at the lab scale, this method becomes difficult to scale up. A scalable method for purification is chromatography; however, separating full capsids (hereafter referred to as "full") that contain the genome from empty capsids (hereafter referred to as "empty") that do not contain the genome and do not contribute to titer has been challenging. When using AAV as a vector for gene therapy, it is desirable to remove empty capsids as much as possible due to their impact on titer and issues related to immunogenicity. This application note introduces a scalable AAV purification process and presents a method for separating empty and full capsids using anion exchange chromatography across multiple serotypes.
