SiliCycle manufactures a variety of HPLC columns for reversed and normal phases applications. The SiliaChrom series contain more than 20 different phases produced in our own laboratories, and we continue to develop additional unique and powerful HPLC columns. In fact, you can be completely assured of the quality, from raw material synthesis through packing, testing and customer applications.
more fun with HPLC valves and a macro lens. The red balls, actually synthetic rubies, are about 3 mm in diameter. The steel cylinders are about 6mm in diameter.
This is a close-up shot of a few resistors on a replacement controller board for a late model HPLC (specifically a Hewlett-Packard 1050).
The lab I've been volunteering at. Behind me is an HPLC machine I helped fix and have been learning to use.
Die LABOMATIC HD-5000 ist eine Weiterentwicklung der bekannten LABOMATIC HD-3000. Wie schon das Vorläufermodell besteht die HD-5000 aus einem System-Controller und einer Pumpenmechanik für einen nahezu pulsationsfreien Fluss. Und wie bei unseren Kunden bekannt ist auch dieses System extrem langlebig, wartungsarm und bietet breite Einsatzmöglichkeiten mit einem Höchstmass an Flexibilität und Funktionalität.
The LABOMATIC HD-5000 is a further development of the established LABOMATIC HD-3000 HPLC pump. Like its predecessor model, the HD-5000 consists of a system controller and pump mechanics for an almost pulsation-free flow. And, as our existing customers will know, this new system is also designed to be extremely durable, low in maintenance and suited for a wide range of preparative HPLC applications with the highest degree of flexibility and comprehensive functionality.
Résumé / Abstract
Ulam raja (Cosmos caudatus) is used traditionally for improving blood circulation. In this study, it was found that ulam raja had extremely high antioxidant capacity of about 2400 mg L-ascorbic acid equivalent antioxidant capacity (AEAC) per 100 g of fresh sample. Antioxidant peaks in extract of ulam raja were firstly characterized using free radical spiking test through high performance liquid chromatography coupled with mass spectrometry (MS). Upon reaction with 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radicals, intensities of antioxidant peaks will be significantly reduced. HPLC/MSn was further applied to elucidate the chemical structures of antioxidant peaks characterized in the spiking test. More than twenty antioxidants were identified in ulam raja, and their chemical structures were proposed. The major antioxidants in ulam raja were attributed to a number of proanthocyanidins that existed as dimers through hexamers, quercetin glycosides, chlorogenic, neo-chlorogenic, crypto-chlorogenic acid and (+)-catching. High content of antioxidants antioxidants contained in ulam raja could be partly responsible for its ability to reduce oxidative stress.

Somehow for the last three years I've sort of flown under the radar for chemistry lab jobs - e.g., "HPLC Guru" when no one in our lab even used the HPLC. My free ride was discovered, however, and I became the "Pre-weekend" stalk up girl. Basically I take a shopping list to the local chem stores every Friday and pick up whatever's needed. It's pretty gross - not only is it in a dingy basement, but I'm fairly certain that filling 24 L of acetone and hexane from big flammable barrels can't be the healthiest thing that I've ever done. Also - if you take a moment for the chemical inventory you may notice that there's a "...ch" and some grapes on a bottle. That's right - some random chemical is being stored in a Welch's grape jam jar.
