Secret Lab LC/MS/MS new main platform: 4500 series

Introduction to the new 4500 LC/MS/MS main platform

The AB SCIEX TripleQuadTM 4500 and QTRAP® 4500 systems are new mass spectrometers, and the TripleQuadTM 4500 is 10 times more sensitive than other triple quadrupole mass spectrometers on the market. The introduction of the AB SCIEX 4500 Series mass spectrometer sets a new benchmark for routine quantification and screening analysis.

Based on feedback from top scientists and application experts in the analytical science community, the 4500 Series mass spectrometer was redesigned on AB SCIEX's existing systems, which will be the latest in mass spectrometry with industry-leading durability.

3 major innovations, 8 inheritances, “high, fast, spiritual”

As a world leader in mass spectrometry, AB SCIEX has launched a series of high-end mass spectrometry products over the past few decades. From 2000, 3000, 3200, 4000 series platforms to 5000 platforms, these mass spectrometry products play an important role in the research of pharmaceuticals and biomarkers. The current 5500 Series mass spectrometer is an innovative instrument that is the benchmark for industry instruments: it represents higher sensitivity, faster scanning speed and better selectivity; it is currently a higher performance series triple quadrupole; It is a performance that is difficult for other competing products. Over the years, customers have been very good at AB SCIEX's 4000 and 5500 platforms. On this basis, AB SCIEX continued to play the excellent quality of the 5500 platform and launched a new 4500 series.

The 4500 mass spectrometer series is based on the 5500 series and is a high-end mass spectrometer. It is more attractive for users who plan to purchase the AB SCIEX mass spectrometer.

The new product 4500 mass spectrometer adopts the design strategy of “innovation + inheritance”. It has the characteristics of “three innovations” and “eight inheritances” and the distinctive features of “high, fast and spiritual”, which enables more laboratories to adopt. State-of-the-art mass spectrometry technology for extensive research and routine measurement.

Three innovations – a new design for the tapered bore, RF electric field, and vacuum system of the 4500 Series mass spectrometer.

(1) New tapered hole design: lower vacuum load and better system stability.
