MASS SPECTROMETRY & SPECTROSCOPY
Soil analysis with NIR spectroscopy
Soil is a complex matrix made of organic and inorganic mineral matter, water, and air. There are many different factors that affect how soil behaves, one of which being the texture of soil which is dependent on the amount of sand, silt, and clay it contains.
Cation-exchange capacity (CEC) is a measure of the ability to hold positively charged ions, and it influences soil structure stability, nutrient availability, pH, and its reaction to fertilisers and other ameliorants.
The main ions associated with CEC in soils are Ca2+, Mg2+, Na+, and K+. Soil pH directly influences the availability of nutrients to plants, microbial activity, and overall soil health, affecting plant growth, and crop yields.
This study describes how organic matter, pH value, silt, clay, sand, calcium and magnesium were measured in soil in seconds by using near-infrared spectroscopy (NIRS). This high-throughput
method not only simplifies lab workflows, but also reduces costs and exposure to chemicals, whilst delivering reliable results for routine soil quality monitoring. By eliminating the need for solvents and extensive preparation, Metrohm’s NIRS solution can enhance both productivity and sustainability in soil testing.

New LCMS-compatible plastic microvials with a permanent marking spot
MicroSolv is excited to announce the launch of its latest innovation in autosampler vials: the LCMS- Compatible Plastic Microvials with a permanent marking spot. These microvials are designed to meet the rigorous demands of modern analytical laboratories.
Each vial features a permanent marking spot, providing clear and lasting identification of samples, essential for accurate tracking and record-keeping.
Manufactured from ultra- pure, virgin, medical-grade polypropylene, the vials are ideal for sensitive applications where high-quality materials are critical to maintaining sample integrity.
The vials are compatible with LCMS applications, as they are free from extractables in most LCMS solvents, ensuring reliable performance in liquid chromatography-mass spectrometry analyses.
Their translucent design allows for easy visual inspection of contents, aiding in sample verification without the need to open the vial.
The flat bottom design enhances needle reach and minimises bubble formation,
LC-MS ADVERTORIAL
optimising sample recovery and accuracy during automated processes.
Produced in an ISO 9001:2015 certified facility, the vials meet the highest standards of quality and reliability, offering confidence in their consistent performance across applications.
The LCMS-Compatible plastic microvials are particularly popular for bio-analysis with aqueous samples and samples that react with glass. Their narrow mouth design and 300ul total fill
capacity make them an excellent choice for autosampler vials. These vials are available with both a 9 mm thread for screw caps and an 11 mm snap top. Both vials have a 12x32 mm outer dimension.
For further details about the LCMS- Compatible Plastic Microvials, please visit the product webpages 9532S-W-MS & 9532C-W-MS, or contact the customer service team.

Solve bioassay challenges: Fluorescence-free, UV-transparent, solvent-resistant quartz plates
Researchers measuring protein at 280 nm or nucleic acids at 260 nm face persistent problems: the microplates themselves interfere with readings. Below 320 nm, plastic and plastic-bonded plates absorb significantly whilst generating background fluorescence, creating noise that compromises sensitivity – particularly frustrating with low-concentration samples.
Starna Scientific’s monolithic quartz 96-well plates address these limitations through full synthetic quartz construction. Heat-fused without adhesives, these single-piece plates deliver complete UV-Vis transmission from 180 nm where plastic alternatives simply cannot perform.
But optical performance is only part of the story. Quartz withstands aggressive solvents, DMSO, DMF, strong acids, that would dissolve or deform plastic plates. It also survives repeated autoclaving at 121°C without warping or leaching contaminants, supporting indefinite reuse and sustainable laboratory practices.
Manufactured under ISO 9001 quality management, each plate delivers consistent performance over years of use. Standard specifications include 300 µL well capacity and 2 mm flat base geometry, ensuring compatibility with conventional plate readers. The fluorescence-free, single-piece construction eliminates contamination risks whilst enabling sensitive assays where signal- to-noise ratio is paramount.
For demanding research in biopharmaceutical development, clinical diagnostics, and academic laboratories, these capabilities prove essential when measuring low-concentration samples with maximum sensitivity and reproducibility.
