Agilent Intuvo 9000GC / 5977C MSD

The integration of gas chromatography with mass spectrometry provides a unified platform for small-molecule characterization, serving as a bridge between synthetic design and biological discovery. In chemical synthesis, the system is primarily used to map reaction pathways by identifying transient intermediates, verifying product purity, and quantifying side-products. This same analytical logic extends to biological applications, where the instrument profiles the chemical “output” of a system—such as metabolites, signaling lipids, or volatile organic compounds (VOCs)—to understand cellular health or metabolic flux.

Recent application: Identification of compounds in the essential oils of different hemp varieties after hydrodistillation. Seventy-nine compounds were identified in the extracts, including major volatile components α-pinene, β-myrcene, α-humulene, and α-terpineol. The GC-MS analysis also utilized the resident NIST spectral library.

Thermo Fisher Scientific Exactive Plus with UltiMate 3000 UHPLC System

The Thermo Fisher Scientific Exactive Plus utilizes high-resolution Orbitrap technology to provide the precise molecular weight measurements necessary for identifying unknown compounds and confirming synthetic yields. It is used for formula verification of new molecules, tracking biotransformations in metabolic studies and enzymatic processes, and analyzing complex mixtures where overlapping signals require high mass accuracy to resolve. Its ability to perform rapid, full-scan analysis makes it a reliable tool for both purity assessment and the screening of small-molecule libraries. Any molecule that can be ionized using electrospray in slightly aqueous conditions and produces an ion under m/z 6,000, including transition metal complexes, is appropriate for analysis.

Recent Application: This system was used to verify and quantify a novel cobalt-quaterpyridine adjuvant essential to functionalize a crystalline carbon nitride semiconductor designed to chemically reduce CO₂.

Bruker Autoflex maX MALDI-TOF

The Bruker Autoflex maX utilizes MALDI-TOF technology to provide rapid mass analysis of large, non-volatile molecules that are difficult to ionize by other methods. In chemical synthesis, it is primarily used for the characterization of polymers and large synthetic complexes, allowing for the determination of molecular weight distributions and end-group analysis. In addition, (peptides, dyes, monomers, other)Within biochemical applications, it serves as a high-throughput tool for protein identification (peptide mass fingerprinting), monitoring post-translational modifications,

**We encourage groups that routinely use the instrument to invest in their own target (Bruker Part No:8280784 or 8280781 depending on application.). By adopting a dedicated target plate, you eliminate the risk of cross-contamination and “chemical memory” from previous users, ensuring that your mass spectra remain free of exogenous peaks or polymer interference. This approach also optimizes your workflow, allowing for offline sample preparation in your own laboratory, which minimizes instrument idle time. Furthermore, owning your target ensures consistent surface quality; by following strict, internal cleaning protocols, you preserve the plate’s integrity, which is essential for achieving the high mass resolution and reproducible calibration required for publication-quality data.**

Thermo Fisher Scientific iCAP RQ ICP-MS 

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) provides precise quantitative analysis of elemental composition, typically measuring over 45 different elements (highlighted in the above figure) at trace levels. In chemistry, the technique is used to verify the elemental purity of synthetic compounds and to detect residual catalysts or metallic contaminants within complex mixtures. For biochemical applications, it facilitates the study of metallomics by quantifying essential and toxic trace metals in biological matrices such as tissues, blood, and plant materials, supporting research into metal-protein interactions and metabolic homeostasis.
