Summary
Automated solid phase extraction (aSPE) using the PrepLinc platform offers a time-saving alternative to manual methods for analyzing environmental lipid biomarkers. This automated approach provides comparable results to manual SPE (mSPE) with higher recovery rates, enhancing paleoclimate research.
Area of Science:
- Geochemistry
- Organic geochemistry
- Paleoceanography
Background:
- Lipid biomarkers in sediments, such as C37 alkenones from microalgae, are crucial for reconstructing past ecosystems and inferring environmental conditions like sea surface temperature.
- Traditional manual solid phase extraction (mSPE) for biomarker analysis is time-consuming and involves hazardous organic solvents, posing health and environmental risks.
Purpose of the Study:
- To compare the efficiency and effectiveness of a routinely applied manual SPE (mSPE) method with an automated SPE (aSPE) method using the PrepLinc platform.
- To evaluate the impact of automated sample preparation on the analysis of environmental lipid biomarkers.
Main Methods:
- Comparison of manual SPE (mSPE) and automated SPE (aSPE) using the PrepLinc platform for sample preparation.
- Analysis of lipid biomarkers from marine sediment samples using gas or liquid chromatography and mass spectrometry.
- Statistical analysis of results obtained from both mSPE and aSPE methods.
Main Results:
- Automated SPE (aSPE) yielded statistically similar results to manual SPE (mSPE) for lipid biomarker analysis in marine sediments.
- aSPE demonstrated a higher recovery rate for biomarkers compared to mSPE.
- The PrepLinc platform, enabling aSPE, processed up to 27 samples in a single run within a closed system, saving time and fume hood space.
Conclusions:
- The PrepLinc platform offers a valuable automated solution for solid phase extraction of environmental lipid biomarkers, ensuring high repeatability.
- Automated SPE (aSPE) is a viable and efficient alternative to mSPE, potentially improving the speed and safety of paleoclimate proxy analysis.
- While aSPE shows advantages in recovery and throughput, careful consideration of compound co-elution is necessary for accurate analysis.

50.2K
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

20.7K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.

02:22Structures of Solids
17.8K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

02:31Phase Transitions
23.2K
Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
