The next generation to Core Shell particle Features of SunShell *. µm of core and 0. µmof superficially porous silica layer *Same efficiency and high throughput as a Sub µm particle *Same pressure as a µm particle (less than a half then a sub µm particle) *Same chemistry as Sunniest technology (reference figure ) *Good peak shape for all compounds such as basic, acidic and chelating compounds *High stability ( ph range for SunShell C8,. to 0) * Low breeding. µm 0. µm Core 0. µm. µm Core Porous silica Schematic diagram of a core shell silica particle. µm Superficially porous silica H H Final TMS H Schematic diagram of bonding of SunShell C8 H Van Deemter Equation A term : Eddy diffusion(dp is particle diameter) B term : Longitudinal diffusion (Dm is diffusion coefficient) C term : Mass transfer B term A term Van Deemter plot u C term HETP, µm m Comparison of plate height plots Fully porous um Fully porous um 0 0 Mobile phase velocity, mm/sec Fully proous.8 um SunShell. um Fully porous. um C8, 0 x. mm C8 Mobile phase: Acetonitrile/water=(0/0) Temperature: o C Sample : Naphthalene Back pressure, MPa Flow rate, ml/min Sunniest C8-HT.0 um Brand A C8.9 um Brand B C8.8 um Brand C C8. um Brand D C8. um SunShell C8. um Column dimension: 0 x. mm Mobile phase: Acetonitrile/water=(0/0) Temperature: o C Comparison of back pressure for high throughput columns SunShell C8 shows same efficiency as a sub µm C8. In comparison between fully porous. µm and core shell. µm (SunShell), SunShell shows lower values for A term, B term and C term of Van Deemter equation. The core shell structure leads higher performance to compare with the fully porous structure. Furthermore back pressure of SunShell C8 is less than a half to compare with sub- µm C8s.

Wide particle distribution (Conventional silica gel D 90 /D 0 =.0) Flow of mobile phase Narrow particle distribution (core shell silicad 90 /D 0 =.) 0. (µm) Comparison of Particle ze Distribution Packing state of core shell and fully porous silica The size distribution of a core shell (SunShell) particle is much narrower than that of a conventional fully porous particle, so that the space among particles in the column reduces and efficiency increases by reducing Eddy Diffusion (multi-path diffusion) as the A term in Van Deemter Equation. Comparison of diffusion path As shown in the left figure, a core shell particle has a core so that the diffusion path of samples shortens and mass transfer becomes fast. This means that the C term in Van Deemter Equation reduces. In other words, HETP (theoretical plate) is kept even if flow rate increases. A. µm core shell particle shows as same column efficiency as a fully porous sub- µm particle. The right figure shows that a diffusion width of a sample in a. µm core shell particle and a µm fully porous particle. Both diffusion widths are almost same. The. µm core shell particle is superficially porous, so that the diffusion width becomes narrower than particle size. Same diffusion means same efficiency.

Brand D C8 showed only a half retention to compare with SunShell C8. Steric selectivity becomes large when ligand density on the surface is high. SunShell C8 has the largest steric selectivity so that it has the highest ligand density. This leads the longest retention time. Comparison of pyridine Comparison of xine Comparison of formic acid Brand D C8 Brand D C8 Brand D C8 Brand E C8 Brand E C8 Brand E C8 SunShell C8 (Core Shell) SunShell C8 SunShell C8 0 Brand D C8,. µm 0 x. mm Brand E C8,. µm 0 x. mm SunShell C8,. µm 0 x. mm Mobile phase: CH H/H =0/0 Flow rate:.0 ml/min Temperature: 0 ºC Detection: UV@0nm Sample: = Uracil = Pyridine = Phenol Brand D C8,. µm 0 x. mm Brand E C8,. µm 0 x. mm SunShell C8,. µm 0 x. mm Mobile phase: CH CN/0mM H P =0/90 Flow rate:.0 ml/min Temperature: 0 ºC Detection: UV@0nm Sample: = 8-Quinolinol (xine) = Caffeine Brand D C8,. µm 0 x. mm Brand E C8,. µm 0 x. mm SunShell C8,. µm 0 x. mm Mobile phase: CH CN/0.% H P =/98 Flow rate:.0 ml/min Temperature: 0 ºC Detection: UV@0nm Sample: = Formic acid = Acetic acid = Propionic Acid Residual silanol groups make pyridine be tailing under methanol/water mobile phase condition. nly SunShell C8 shows a sharp peak for pyridine. 8-Quinolinol (xine) is a metal chelating compound. Metal impurities in the core shell particle leads the tailing for oxine peak. Formic acid is used as an indicator for a acidic inertness. SunShell and brand D C8 show a sharp peak.
5 Loading capacity of amitriptyline as a basic compound Amitriptyline overlords much more at acetonitrile/buffer mobile phase than methanol/buffer. Three kinds of core shell C8s were compared loading capacity of amitriptyline at three different mobile phases. Common condition: Column dimension,0 x. mm, flow rate;.0 ml/min, temperature; 0 o C Mobile phase: Acetonitrile/0mM phosphate buffer ph.0=(0:0) Mobile phase: Acetonitrile/0mM acetate ammonium ph.8=(0:0) 00 times 0 times SunShell C8 Brand D C8 Sample: = Uracil (0.0µg) = Propranolol (.µg) = Nortriptyline (0.µg) = Amitriptyline (0.µg) SunShell C8 Brand D C8 Brand E C8 Brand E C Theoretical plate was calculated by σ method using peak width at.% of peak height..% Mobile phase: Acetonitrile/0.% formic acid=(0:0) USP tailing factor..9. times.8. Amitriptyline overloads at low weight when acetonitrile/0.% formic acid mobile phase. A peak is shifted forward under overloading. Brand D C8 overloaded at more than 0.0 µg of amitriptyline while SunShell C8 overloadsed at more than from 0. to µg of amitriptyline. Surprisingly loading capacity of Brand D C8 was only one hundredth to compare with SunShell C8 under acetonitrile/0mm phosphate buffer ph.0=(0:0) mobile phase. Brand E C8 always showed poor peak of amitriptyline.

SunShell C8 is to 0 times more stable than the other core shell C8. ) N. Nagae, T. Enami and S. Doshi, LC/GC North America ctober 00. ) T. Enami and N. Nagae, American Laboratory ctober 00. ) T. Enami and N. Nagae, BUNSEKI KAGAKU, (00) 09. Durable test condition Column ze: 0 x. mm Mobile phase: CH H/0mM Sodium borate/0mm NaH=0//9 (ph0) Flow rate: 0. ml/min Temperature: 0 ºC Measurement condition Column ze: 0 x. mm Mobile phase: CH CN/H =0/0 Flow rate: 0. ml/min Temperature: 0 ºC Sample: = Butylbenzene Stability under basic ph condition was evaluated at 0 ºC using methanol/sodium borate buffer ph 0 (0:0) as mobile phase. Sodium borate is used as a alkaline standard solution for ph meter, so that its buffer capacity is high. Elevated temperature of 0 ºC makes column life be one third. The other company shows stability test at ambient (room temperature). If room temperature is ºC, column life at room temperature ( ºC) is sixteen times longer than that at 0 ºC. SunShell C8 is enough stable even if it is used under ph 0 condition. Regarding stability under basic ph condition, there is little C8 column like SunShell C8 except for hybrid type C8. It is considered that our end-capping technique leads high stability. SunShell C8 can be used at the ph range from. to 0.

C8 showed the highest hydrophobicity and PFP showed both the highest steric selectivity and the highest hydrogen bonding. The feature of PFP phase is to have hydrogen bonding, dipole-dipole interaction, aromatic and pi-pi interactions and hydrophobicity, which causes a different selectivity from a C8 phase.
