Hewlett Packard, now known as HP, is a renowned technology company that has made significant contributions to various industries. One of their notable achievements is in the field of chromatography. Chromatography is a widely used technique in chemical analysis, allowing scientists to separate and identify different compounds in a sample. HP has played a pivotal role in advancing chromatographic instrumentation, particularly in gas chromatography (GC) and liquid chromatography (LC).
The Role of Gas Chromatography in Chemical Analysis
Gas chromatography is a technique that utilizes an inert gas as the mobile phase to separate and analyze volatile compounds. HP has developed advanced instrumentation for gas chromatography, making it a powerful tool in chemical analysis.
GC instruments manufactured by HP are equipped with computer-controlled pressure and temperature settings, allowing for precise control and automation. This ensures accurate and reproducible results. These instruments also feature automated sample changers, enabling high-throughput analysis.
HP's gas chromatography systems are compatible with various detectors, including conductivity (CD), flame ionization (FID), and electron-capture (ECD) detectors. These detectors offer compound-specific detection, enhancing the sensitivity and selectivity of the analysis.
In addition to organic compounds, HP's gas chromatography instruments can also be coupled with atomic spectrometric detectors for metal determinations. This allows for the analysis of inorganic compounds by transforming them into appropriate organometallic compounds.

Liquid chromatography, particularly high-performance liquid chromatography (HPLC), is another powerful analytical technique used in various industries. HP has made significant advancements in HPLC instrumentation, making it more efficient and reliable.
Unlike gas chromatography, liquid chromatography utilizes a liquid mobile phase. This allows for the analysis of thermally less stable compounds, as the working temperatures are comparatively low.
HP's liquid chromatography systems are designed to operate at elevated pressures, which increases the efficiency of the separation process. However, this also makes liquid chromatography more expensive compared to gas chromatography.
HP's HPLC instruments are compatible with various detection methods, including spectrophotometric, electrochemical, and atomic spectrometric methods. These detectors allow for the analysis of a wide range of compounds, including metals.
The Significance of Ion Chromatography
Ion chromatography is a specialized form of liquid chromatography that focuses on the separation and analysis of ions. HP has made significant contributions to the field of ion chromatography, enhancing its capabilities and applicability.
