In LC–MS analysis, every step of sample preparation is critical, especially the choice and use of vial caps and septa. This article systematically covers key preparation techniques, including filtration, protein precipitation, solid phase extraction, liquid–liquid extraction, supported liquid extraction, and derivatization. It also explains how to select Aijiren’s pre-slit PTFE/silicone septa, standard septa, and bonded aluminum caps for different workflows to ensure a secure seal and prevent volatilization and contamination. With a comparative product table, readers can clearly understand the advantages and application scenarios of each cap/septa type, enabling greater reproducibility and data accuracy in pharmaceutical development, proteomics, and environmental testing.

This article aims to assist laboratory researchers in identifying and correcting five common operational errors associated with the use of 20mL scintillation vials in radioactive sample analysis.

Minor mishandlings, such as improper sealing or inadequate cleaning, can lead to significant data deviations, with studies indicating up to a 30% variance in results.

The article delves into issues like sealing inadequacies, reuse of uncleaned vials, neglecting chemical compatibility between vial materials and reagents, improper storage leading to contamination, and volume misjudgments causing quenching effects.

By offering detailed solutions and experimental validation data, the article guides researchers in optimizing their experimental procedures to ensure data accuracy and reliability.

Explore the comprehensive guide on 20mL scintillation vials, covering materials like borosilicate glass, specifications including 22-400 thread finish, and applications in radioactive sample analysis, environmental monitoring, and biomedical research.

Chromatographic techniques play a pivotal role in organic compound analysis. This article delves into the principles, applications, and significance of GC, GC-MS, HPLC, and TOC in detecting organic compounds, offering insights to enhance analytical workflows and decision-making.

Optimized for low-volume samples (150–300 µL) to minimize sample loss and ensure analytical accuracy. Compatible with 8‑425, 9 mm, 10‑425, and 11 mm vials for GC, HPLC/UHPLC, and MS workflows.

Aijiren’s Bonded Cap & Septa series (Part No. SC9192–B‑SC92291‑A) delivers 9 mm threaded vial caps with high‑strength seals, chemical‑inert multilayer construction, and color‑coded identification. These caps prevent leaks under extreme conditions, resist solvent attack, and streamline sample handling in chromatography, storage, and high‑throughput workflows.

HPLC Syringe Filters are essential tools for chromatography and lab sample preparation. They precisely remove particulates to protect columns and prevent clogging, while low‑leach housings preserve sample purity. Available membrane materials include Nylon, PVDF, PTFE, PES, MCE, PP, and Cellulose Acetate—suiting pharmaceutical, environmental, biotech, and food‑testing workflows.
