Product Overview

Water Ultra LC-MS is a high-purity solvent engineered for demanding analytical applications where trace contaminants can compromise results. With an ultra-low total organic carbon (TOC) content of less than 0.1 ppb, this water eliminates background interference, ensuring baseline stability in liquid chromatography-mass spectrometry (LC-MS) workflows. The product undergoes rigorous purification processes, including reverse osmosis, deionization, and sub-micron filtration, to remove ionic, organic, and particulate impurities. Its consistent quality meets or exceeds ASTM Type I and ISO 3696 Grade 1 standards, making it suitable for ultra-sensitive detection methods. The packaging is designed to minimize leachables and maintain purity during storage, with tamper-evident seals to prevent contamination. This water is particularly effective in reducing matrix effects in electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI) techniques. Its neutral pH and absence of UV-absorbing compounds ensure compatibility with a wide range of mobile phases and gradient elution protocols. The product’s stability is verified through accelerated aging tests, guaranteeing reliable performance throughout its shelf life.

FAQs

1. What is the maximum allowable TOC level in this LC-MS grade water?

The TOC content is strictly controlled to remain below 0.1 ppb, which is critical for preventing signal suppression in mass spectrometry applications.

2. Can this water be used directly for mobile phase preparation without further filtration?

Yes, the water undergoes 0.22 µm filtration during production, eliminating the need for additional filtration in most LC-MS applications.

3. How does the packaging prevent contamination during storage?

The container uses low-extractable HDPE material with a tamper-evident seal, and the production process includes nitrogen purging to minimize oxygen exposure.
