Common use LC-MS vials types

Quality vials are essential for reliable analytical results. All Waters Certified Vials are tested by LC or LC/MS to assure quality and cleanliness. The test results confirm the vials, cap and septa have been properly manufactured, handled and packaged, and are free

(recommended for LC-MS), 01018-60028 • Aijiren solvent filters show uniform particle size and superior pre-size homogeneity • Aijiren solvent inlet filters are packed in ultraclean antistatic bags with inner metallic coating, while other vendors use normal plastic

for consumption.2 The most common analytical method used by Veterinary Diagnostic Labs for feed analysis is LC-MS/MS. The method presented here quantifies 15 mycotoxins that are monitored in corn-based animal feed using a liquid-liquid extraction and LC

LC/MS system Why and when to use LC/MS The use of LC-MS in many application areas within analytical science continues to grow almost exponentially. Listed below are some pointers as to the applicability of both HPLC as a separative technique and MS

samples (both LC/MS grade) 6 Common Recommendations: Mobile Phase • Symptoms −Peaks shift −Loss of resolution • Causes −Mobile phase pH changes • Prevention − Use correct buffer for pH range. − Control pH of mobile phase.

Mechanical Stability via Fast Gradient Testing The Supelco Discovery LC-MS HPLC columns are rigorously tested in order to provide the highest mechanical stability under repeated gradient cycles. Table 1 shows of the impact on column efficiency, peak shape, retention times and back pressure after 1000 cycles of a 2-minute rapid (ballistic) gradient with 1-minute equilibration

2019/5/28 · LC-MS is a common technique in analytical science, but do you have the optimal LC-MS set-up for your particular application and are you using the correct UHPLC to get the maximum performance from your mass spectrometer?

LC/MS Choose the Bonded Phases Best-Suited for Your LC/MS Separation Very short narrow-bore columns seem ideal for LC/MS. What bonded phase should I use? High Throughput I typically select 4.6 x 250 mm, 5 µm columns for my analytical

LC-MS/MS Maintenance. One key aspect of monthly maintenance is flushing the LC components. Buildup of contaminants from solvents and extracts often causes common problems such as solvent pump failures, carryover, high system pressure, high background, and interferences. Replacement of expensive parts becomes the solution to most of these issues

2010/8/1 · The use of LC-MS/MS can enable the performance of highly accurate analyses. However, the application of this technology is not necessarily translatable into accurate results. The pitfalls of this technology must be recognized and systematically addressed.
